Design and Optimization of FCEV Subframe by Integrated Applications of Hypermesh, UG and ADAMS Multi-Platform

Abstract:

The UG model and finite element model of FCEV subframe are established, and original subframe is simulated in all kinds of ADAMS environment, which result in the force of the conditions obtained. Then the virtual model is build, stiffness and strength analysis are conducted, and a new type of subframe structure is designed based on the analysis results. Magnesium alloy and aluminum alloy are used in optimization of this new structure for the optimal size. Through the comparative analysis on strength, stiffness, mode shape and quality of the new subframe and the original one, it was verified that the new subframe design is reasonable and feasible.
