CONSTANT SPEED ENGINE CONROD SOFT VALIDATION & OPTIMIZATION

The constant speed four stroke reciprocating engine Connecting rod is subjected to variable loading when Engine is in operating condition. Proper optimization of connecting rod is critical for the engine Performance, vibration level & balancing of overall engine. The stresses in Connecting rod are not constant during its operating condition. The stress varies in one complete cycle. The connecting rod traditionally were designed and analyzed under Static axial loading condition. The Quasi-dynamic approach has a considerable effect in design optimization of connecting rod. The finite element analysis of four stroke Diesel engine is considered. Structural systems of connecting rod can be easily analyzed using Finite Element techniques. So firstly a proper a CAD model is developed Pro/E Wildfire 4.0. Then the Finite element analysis is done to determine the Von Mises stresses in the existing connecting rod for the given loading conditions using Finite Element Analysis software ANSYS. The optimization of conrod is done based on the results and validated.
