| Abstract: | It is found that the working safety factor of a bogie gear box suspender is too large during the process of developing and designing. To perform lightweight design, the suspender is optimized by the methods of topology optimization combined with free shape optimization based on OptiStruct. The total mass of suspender is reduced by 38.3% after optimization and the working safety factor and stiffness of the optimized suspender meet the requirements. |
