Structure optimization and casting simulation of engine trestle based on CAE technology

Reasonable structure design is premised on making the product structure lightweight and green production, therefore through the ANAYS sofLare on the structural design and optimization can reduce the process of product development, and improve the efficiency of product design. ANSYS Workbench was used to analyze the conditions of static, dynamic and fatigue characteristics, the trestle structure parameter optimization, and realized the trestle structure optimization design. The simulation results have shown that the optimized trestle weight reduced about 60% compare to the original casting, reduced more than 20% compared with the original change plan. At the same time, the maximum stress value on focused regional reduced by 30% or more, which makes the structure more reasonable. Then the casting process of trestle optimization structure was simulated to verify the optimized parts production feasibility, and effectively predict the casting structure and casting process design flaws, for further optimization of casting process provides important reference by MAGMA software.
