摘　　要：为提高高速列车齿式联轴器的设计效率,优化设计结构,利用CAD/CAE技术开展了一体化设计。利用CAD软件对驱动装置进行三维设计及虚拟装配,并对驱动装置进行运动仿真分析,得到牵引电机在额定转速和最高转速两种运营条件下轮对线速度的大小;采用CAE软件对鼓形齿联轴器进行静强度分析及安全校核,以确保其服役安全性。结果表明,牵引电机在额定转速和最高转速下车轮线速度分别为243.3 km/h和349.1 km/h,满足高速运行条件;鼓形齿联轴器在平衡工况和最大角向位移工况下最大应力分别为391 MPa和403 MPa,满足安全运行的要求。提出的联轴器CAD/CAE一体化设计方法,为其结果优化提供了参考依据。In order to improve the design efficiency of high-speed train gear coupling and optimize the design structure, the CAD/CAE technology is used to carry out the integrated design. The CAD software is used to design and virtually assemble the drive device and a motion simulation analysis of the drive device is conducted, which produce the wheel set linear speed of the traction motor under the rated speed and the maximum speed. The CAE software is used to adjust the drum gear. The coupling is subjected to static strength analysis and safety check to ensure its safety in service;the results show that the linear wheel speed of the traction motor is 243.3 km/h at the rated speed and 349.1 km/h at the maximum speed, respectively, which satisfy high-speed operating conditions. The maximum stress of the drum-shaped gear coupling under balanced conditions and maximum angular displacement conditions are 391 MPa and 403 MPa respectively, which meet the requirements of safe operation. The above-mentioned coupling CAD/CAE integrated design method provides a reference for its optimization.
