Design, Stress and Modal Analysis of Connecting Rod for Linear Opposed Engine

Kolchin. A and V.Demidov (1989) has written a book named Design of Automotive Engines, which includes the overall design of all automotive engine systems with balancing. This is the book translated from the Russian by P.Zabolotnyi. The connecting rod is subjected to a complex state of loading. it undergoes high cyclic loads of the order of 10 8 to 10 9 cycles, which range from high compressive loads due to combustion, to high tensile loads due to inertia. therefore, durability of this component is of critical importance. Due to these factors, the connecting rod has been the topic of research for different aspects such as production technology, materials, performance simulation, fatigue, etc. for the current study, it was necessary to investigate finite element modeling techniques, analysis techniques, developments in production technology, new materials, fatigue modeling, and manufacturing cost analysis. This project performed three dimensional finite element analysis of a high-speed diesel engine connecting rod. For this analysis they used the maximum compressive load which was measured experimentally, and the maximum tensile load which is essentially the inertia load of the piston assembly mass. The load distributions on the piston pin end and crank end were determined experimentally. They modeled the connecting rod cap separately, and also modeled the bolt pretension using beam elements and multi point constraint equations. based on fatigue tests carried out on identical components made of powder metal and c-70 steel (fracture splitting steel), he notes that the fatigue strength of the forged steel part is 21 % higher than that of the powder metal component. it also notes that using the fracture splitting technology results in a 25% cost reduction over the conventional steel forging process. These factors

Design, Analysis and Optimization of Connecting Rod

Automobile industry always require cost efficient and high quality product. This gives us an opportunity to study design methodology so as to improve and provide industrial requirement. The time spent in trial and error analysis in the design process need to be eliminated in order to sustain in this fast moving market. Therefore, computational methods have been used in early stage of the design. Finite element method is applied for modal analysis and structural analysis of connecting rod. Modal analysis is the process of determining the inherent dynamic characteristics of a system in form of natural frequencies, damping factors and mode shapes, and using them to formulate a mathematical model for its dynamic behaviour. Whereas structural analysis gives an idea about stress distribution at loading condition. Mesh determination is too critical in order to ensure that the best mesh size is to be used in carrying out the analysis for other parameter involved. As stability and convergence of various mesh processing applications depend on mesh quality, there is frequently a need to improve the quality of the mesh.

DESIGN AND ANALYSIS OF CONNECTING ROD: A REVIEW

4.Pushpendra Kumar Sharma, Borse Rajendra R.(2012), The main aim of this research is to determine total Fatigue Analysis in the existing Connecting rod. If the existing design shows the failure, then suggest the minimum design changes in the existing Connecting rod. In this research only the static FEA of the connecting rod has been performed by the use of the software & the combination of finite element technique with the aspects of failure reduction is to be made to obtain the required design of connecting rod. A fatigue analysis can be separated into 3 areas: materials, analysis, and results evaluation. A large part of a fatigue analysis is getting an accurate description of the fatigue material properties. These properties are included as a guide only with intent for the user to provide his/her own fatigue data for more accurate analysis. Fatigue results can be added before or after a stress solution has been performed. To create fatigue results, a fatigue tool must first be inserted into the tree. This can be done through the solution toolbar or through context menus. The details view of the fatigue tool is used to define the various aspects of a fatigue analysis such as loading type, handling of mean stress effects and more. Several results for evaluating fatigue are available to the user. Outputs include fatigue life, damage, factor of safety, stress biaxiality, fatigue sensitivity.

Modern Optimized Design Analysis of Connecting Rod of an Engine

components of the engine assembly, it acts as a mediator between piston assembly and crankshaft. It started from the sawmills to the engine various transmission forces. The connecting rod connects reciprocating piston to rotating crankshaft, transmitting the thrust of the piston to the crankshaft. It has two ends. The small end is connected to the piston by a gudgeon pin while other end is connected crankshaft using crank pin. The reciprocating motion generated during the transmission of brake power at piston head causes various stress to acts on the connecting rod. It is generally use to transmit the force through mechanism. So, it is important to reduce the weight with the consideration of the permissible limit for manufacturing of better connecting rod. This further analysis move towards von misses stress so that we get the better component with reduced weight, cost effective and provide better result than other components.

Design Analysis of Connecting Rod and Crank Shaft

(1450 psi), while contemporary high-performance Compression-Ignition (CI) engines can see combustion pressures in excess of 200 bar (2900 psi). A pressure of 100 bar acting on a 4.00 inch diameter piston will produce a force of 18,221 pounds. A pressure of 200 bar acting on a 4.00 inch diameter piston produces a force of 36,442 pounds. That level of force exerted onto a crankshaft rod journal produces substantial bending and torsional moments and the resulting tensile, compressive and shear stresses. However, there is another major source of forces imposed on a crankshaft, namely Piston Acceleration. The combined weight of the piston, ring package, wristpin, retainers, the conrod small end and a small amount of oil are being continuously accelerated from rest to very high velocity and back to rest twice each crankshaft revolution. Since the force it takes to accelerate an object is proportional to the weight of the object times the acceleration (as long as the mass of the object is constant), many of the significant forces exerted on those reciprocating components, as well as on the conrod beam and big- end, crankshaft, crankshaft, bearings, and engine block are directly related to piston acceleration. Combustion forces and piston acceleration are also the main source of external vibration produced by an engine.

Design and Analysis of Connecting Rod and Piston Crankshaft by Using Ansys

As a result of heat transfer, an intense and unsteady heating of every part of the group occurs. Temperature level of the piston, exhaust valve, cylinder head, valve seats and other parts may attain to the limiting values in terms of mechanical properties of structural materials. In some cases there might be a harmful overheating of details which results in a burnout of piston head, cracking of the walls of the combustion chamber and other effects that lead to the destruction of the engine. Thus, special measures to ensure optimum thermal regime of the main parts of the engine are required for its regular operation.

Design and Buckling Analysis of Two Wheeler Connecting Rod Using Different Materials Borra Ramesh Babu, Sri Dr K Hari Babu & Krishna Veni K

A major source of engine wear is the sideways force exerted on the piston through the connecting rod by the crankshaft, which typically wears the cylinder into anoval cross-section rather than circular, making it impossible for piston rings to correctly seal against the cylinder walls. Geometrically, it can be seen that longer connecting rods will reduce the amount of this sideways force, and therefore lead to longer engine life. However, for a given engine block, the sum of the length of the connecting rod plus the piston stroke is a fixed number, determined by the fixed distance between the crankshaft axis and the top of the cylinder block where thecylinder head fastens; thus, for a given cylinder block longer stroke, giving greater engine displacement and power, requires a shorter connecting rod (or a piston with smaller compression height), resulting in accelerated cylinder wear.

Design and Analysis of 150CC IC Engine Connecting ROD

Injection molding: It is a fast, high-volume, low- pressure, closed process using, most commonly, filled thermoplastics, such as nylon with chopped glass fiber. In the past 20 years, however, automated injection molding of BMC has taken over some markets previously held by thermoplastic and metal casting manufacturers. For example, the first-ever BMC-based electronic throttle control (ETC) valves (previously molded only from die-cast aluminum) debuted on engines in the BMW Mini and the Peugeot 207, taking advantage of dimensional stability offered by a specially-formulated BMC supplied by TetraDUR GmbH (Hamburg, Germany), a subsidiary of Bulk Molding Compounds Inc. (BMCI, West Chicago, Ill.,). In the BMC injection molding process, a ram- or screw- type plunger forces a metered shot of material through a heated barrel and injects it (at 5,000 to 12,000 psi) into a closed, heated mold. In the mold, the liquefied BMC flows easily along runner channels and into the closed mold. After cure and ejection, parts need only minimal finishing. Injection speeds are typically one to five seconds, and as many as 2,000 small parts can be produced per hour in some multiple-cavity molds.

Comparison of the Materials for the Connecting Rod in ANSYS by using Fem Tool

The Finite Element Analysis (FEA) or Finite Element Method (FEM) is a numerical procedure, which could give close precise answers for complex field issues. Fundamentally this technique includes separating the intricate structures into known number of littler structures or components. This capacity of the strategy is called discretization or cross section, which makes the method more viable in breaking down sporadic molded structures in an assortment verity of designing issues. The conventional item advancement process depends on crucial building conditions and powerful in breaking down customary molded basic issues. However for complex physical issues the outline procedure is more reliant on broad testing, which typically makes the procedure costly. The cutting edge item advancement process with FEA innovation does not kill the item testing process, but rather its capacity to examine complex physical issue effortlessly and successfully can diminish the underlying model testing in the plan phases of the item improvement process.

Design Assembly and Static- Dynamic Analysis of 5 Cylinder Radial Engine

The radial engine is a reciprocating type internal combustion engine configuration in which the cylinder radiates outward from a central crankcase like a spoke of wheel. The radial configuration was commonly used for aircraft engine. Designing of a radial engine is a very complicated process which involves serious of other processes that are hard to be designed. It takes a very long time of thinking of the proper dimensions, proper material (default aluminum) and even the proper shape of all different parts. It has crank case that is a little bit different than the other engines but although that is hard to be figured out too. It also has pistons, cylinders, connecting rods, The designing is done through CATIA V5 software and the analysis process has been completed through ANSYS14.5. Although nowadays used radial engine is a little engine that was not in the beginning of the aerospace transportation. Now radial engine is very helpful and mainly used because of its small weight and size. That makes it comfortable and suitable for any machine that is close of space. Despite of its small size and weight it does not make it less powerful than other engines. It was also comfortable for the World War II airplanes when the engine was in its peak. When it is war you need more space for fuel, power, weapons and bullets than any other things and than any other time. So radial engine was a great invention. By using different material analysis is done through ANSYS. All though materials are Phoshorized navel brass, Titanium alloy, aluminum alloy(default aluminum). Static and model analysis is done on Master Connecting Rod using different materials and followed by structural and analysis on sleeve piston connecting rod assembly on titanium and aluminum.

Modelling and Analysis of Connecting Rod

Abstract: Connecting rod is one among the foremost necessary half in automotive engine. Connecting rod is that the link between piston and crankshaft. Which it converts reciprocatory motion of piston into motion of crankshaft. In internal engines connecting rod is mainly made of steel and aluminium alloys (for light weight and absorb high impact loads) or titanium (for higher performance engines and for higher cost). As a connecting rod is rigid, it may transmit either a push or apull and then the rod could rotate the crank through each halves of a revolution, i.e. Piston pushing and piston pulling. Earlier mechanisms, such as chains, could only pull. In a few two-stroke engines, the connecting rod is only required to push. In which it undergoes structural deformations. Thus in this project we are modelling a connecting rod in catia V5R20 design software and doing static structural analysis in ansys work bench 17.0 software.

Weight Optimization Static and Dynamic Analysis of Connecting Rod with Composite Material

Connecting rod is one of the most important part in automotive engine. Connecting rod is the link between piston and crank shaft. Which it converts reciprocating motion of piston into rotary motion of crank shaft. In internal engines connecting rod is mainly made of steel and aluminium alloys (for light weight and absorb high impact loads) or titanium (for higher performance engines and for higher cost) or composite materials , composite materials is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. As a connecting rod is rigid, it may transmit either a push or a pull and so the rod may rotate the crank through both halves of a revolution, i.e. Piston pushing and piston pulling. Earlier mechanisms, such as chains, could only pull. In a few two- stroke engines, the connecting rod is only required to push. In which it undergoes structural deformations.
