Control arm lightweight optimization design method under stamping of veneer

The invention discloses a control arm lightweight optimization design method under stamping of a veneer. Firstly, load extraction and performance analysis on a control arm of a benchmarking vehicle model are finished through the method of combination of test and simulation, a topological optimization means is applied in the earlier stage of structural optimization, unnecessary materials are greatly reduced, a design conceptual scheme is provided rapidly, but as the obtained structural outline is dim, shape is not regular and machining is not easy, it is necessary to geometrically modify the optimization result, then the modified structure will deviate from the optimal structure more or less, the structural details are continuously optimized through the means such as topography optimization, dimension optimization, shape optimization and free shape optimization, and an optimal result is obtained. Finally, through performance analysis and comparison of the control arm before and after design, it is proved that by application of the design method, lightweight optimization design of the control arm under stamping of the veneer can be finished efficiently and economically.
