Abstract:In order to improve the fatigue strength of parts，enhance product quality and save costs，taking the damage of box parts in impact test as an example，the product structure and parts damage are analyzed，and the finite element analysis and optimization design are carried out.The Simulation software is used to analyze the fatigue strength of the box parts，view the stress and deformation nephogram，and quickly locate the weak points of the structure.The structural strength is improved by increasing the stiffened plate，increasing the thickness or reinforcing the boss；simulation result analysis and impact test of products are conducted.It is pointed out that the mass of the optimized box increases by 2.5%，the overall shape is basically unchanged，the mechanical interface is unchanged，and the box parts are not damaged,and using finite element analysis to optimize structural design of parts can shorten the cycle of new product development and save the R&D costs.
Key Words:finite element analysis；fatigue strength；impact test；boundary constraints；stress deformation nephogram
