261 Topology Optimization to Design of Connecting Rod

This paper explores t to develop structural modeling, finite element analyze and the optimization of the connecting rod for robust design using topology optimization technique. The structure of connecting rod was modeled utilized computer aided design software. Finite element modeling and analysis were performed using finite element commercial software. Linear static analysis was carried out to obtain the stress/strain state results. The mesh convergence analysis was performed to select the best mesh for the analysis. The topology optimization technique is used to achieve the objectives of optimization which is to reduce the weight of the connecting rod. From the FEA analysis results, TET10 predicted higher maximum stress than TET4 and maximum principal stress captured the maximum stress. The crank end suggests being redesign based on the topology optimization result. The optimized connecting rod is 11.7% lighter and predicted low maximum stress compare to initial design. For future research, the optimization should cover on material optimization to increase the strength of the connecting rod.
