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 Optimization and Comparative Stress Analysis of Connecting Rod using Finite Element Analysis
A connecting rod is an important member of the engine assembly accompanied by mass production all over the world. Moreover it possesses great opportunity for research and development in terms of its material and its design parameters. In the present research work initially modelling of connecting rod was done in ANSYS 14.5 software and then analysed in again ANSYS 14.5 software itself. Analysis was mainly focussed on design parameters and its material .Then best design parameters and best material was chosen.
