Abstract
In order to realize the weight-lightening of SUVs on the base of meeting each performance requirement under complex work conditions,automobile steering knuckle was studied.Topology optimization of continuum structure with variable density and compromise programming method were combined to propose a multi-objective optimization function model,and analytic hierarchy process are used to determine the relative weight of each sub target and to conduct multi-objective topology optimization.Optimization resulted in ideal distribution of materials.The comparative analysis of static and dynamic characteristics showed that the optimization improved the stiffness and natural frequency of the structure on the base of automobile weight-lightening,thus realizing the multi-objective optimization.关键词
