Abstract
To design lightweight jack rack and improve the coefficient of the material utilization,this paper does its static analysis in four extreme conditions and knowns that its stiffness and strength is higher,and the material can not be fully utilized in the four condi-tions.Topology optimization for the rack makes the rack structure get the best material distribution.According to the optimized struc-ture,the rack model is re-established and its finite element analysis is done to verify the reliability of the results. After the optimiza-tion,the mass of the rack is reduced from 26.714 kg to 21.058 kg,reduced by 21.17%. It meets its requirements and the coefficient of the material utilization is improved greatly.关键词
