摘　　要：为提高转向架轮对的设计效率,基于参数化设计理论,提出了一种面向性能的参数化设计方法.通过轮对结构参数与动力学、强度性能参数的关联分析,提取轮对的关键设计参数,并以此实现三维参数化自动建模,进而进行模型的动力学及强度评价,通过修改关联设计参数,以实现快速优化设计.基于此开发了高速转向架轮对参数化设计系统,并验证了所确定的设计参数的合理性及设计方法的准确性.To improve the design efficiency of wheelsets of high-speed bogie,aperformance oriented parametric design method is proposed based on the parametric design theory.The core design parameters of the wheel are identified on the basis of the correlation analysis between structural parameters and dynamics,and structural parameters and strength performance parameters.By using these design parameters,the parametric 3Dmodel of wheelsets is modeled automatically.The dynamics and strength can be analyzed by 3D model of the wheelset.The design optimization can be actuated quickly by modifying the associated design parameters.The result of the example shows that the design parameter of wheelsets and the design method are reasonable and accurately.
