Abstract
A multi-objective topology optimization for the control arm of vehicle suspension is conducted with the compliance (static state) under multi-conditions and the natural frequency of vibration (dynamic state) as objective functions. Based on the SIMP method of topology optimization and combining multilevel tolerant sequential programming approach with compromising programming scheme, first the frequency optimization under free vibration condition and then the compliance optimization at static condition are performed in sequence. Finally, a topological structure of control arm is obtained meeting the both requirements of minimum compliance at static state and highest low-order frequency under dynamic vibration.
