针对无法全面评价转向架刚度性能的问题,介绍了采用Solidworks平台开发的新型5自由度转向架刚度试验台虚拟样机的设计过程和结构原理,为设计转向架提供了理论依据。 Aiming at the problem that the rigidity performance of the bogie can not be fully evaluated, the design process and structure principle of the new virtual prototype with 5 degrees of freedom bogie rigidity test bench developed by Solidworks platform are introduced, which provides a theoretical basis for the design of the bogie.
