Optimizing the Design of Connecting Rod under Static and Fatigue Loading
The main objective of this work is to re-optimize the existing design of connecting rod of universal tractor (U650) by changing some of the design variables. The existing design performs modelling and evaluates critical regions in the connecting rod under fatigue loading. In the present work, the model is developed, analyzed and designed using CATIA 19, PRO-E and ANSYS workbench v12. Optimization of connecting rod is done under same boundary and loading conditions for variation in the few stress and fatigue parameters i.e. stresses, weight, life, damage, bi-axiality indication and safety factor. The allowable numbers of cycles under fully reversed fatigue loading are increased and assumed up to a maximum limit of 10 cycles. Stress concentration coefficient is varied to obtain the maximum cycles condition. The critical regions under both static and fatigue analysis are identified and improved. The connecting rod is modelled and optimized for the reduced weight, improved life and manufacturability. The results obtained from performed analysis can be used to modify the design of existing connecting rod, so that better performance i.e. reduced inertia, fatigue life and manufacturability can be obtained under varying static and fatigue conditions.
DESIGN AND OPTIMIZATION OF CONNECTING ROD FOR 4 - STROKE PETROL ENGINE BY USING FINITE ELEMENT ANALYSIS
The connecting rod is the mediating member between the piston and the Crankshaft. Its main function is to convert the reciprocating motion of the piston into rotary motion of the crank. This paper describes about a real time problem of using Cast Iron connecting rod in Hero Honda Splendor + motorbike it’s modelling and analysis and optimization of connecting rod. Here, the connecting rod is replaced by various materials like stainless steel, aluminium, C70 steel and also a design change by inducing truss member is suggested. The connecting rod is modelled using CATIA software for both existing solid and modified truss designs. Boundary conditions are applied to the models after finishing the pre – processing work in ANSYS 14.0 software. The best combination of parameters like Von misses stress and strain, Deformation, Factor of safety, fatigue and life cycle calculation, bi-axiality indication for two wheeler piston were done in ANSYS 14.0 software. This project also tends to optimize the design by calculating weight and stiffness for various materialistic designs by using the output values of mass and volume of the connecting rod which will also be obtained from the software. This paper will conclude whether the modified design is safe along above selected materials. And will be presenting the best design for future reference.
