【Abstract】 Based on the failure situations of the steering gear bracket in loading experiment,stress conditions were analyzed when bracket was in limit positions. Finite element statics analysis techniques and ANSYS Workbench were applied for getting the results of stress and deformation during extreme working conditions. According to the analysis results,combined with the techniques of size optimization,shape optimization and topology optimization,aiming at reducing the maximum stress of dangerous position,the quality of bracket and enhancing structural stability,the steering gear bracket was optimized. The experimental results provided by company demonstrated that the stress a nd deformation situation were improved compared with original model and the optimized object of lightweight was achieved.更多还原
