CRH3型动车组是中国当下运行速度最快的动车车辆,其驱动装置采用架悬式,有别于其他常见的轴悬式和体悬式。牵引电机是动力转向架驱动装置的重要组成之一,西门子公司对CRH3型车的电机安装采用板弹簧结构悬于构架上,不仅能够承载电机自重,而且减弱了运行过程中由牵引电机带来的摇头惯量。这一结构设计的巧妙性不言而喻。本文将通过Solid Works软件参照CRH3型动车转向架建立等比例的三维模型,然后通过SIMPACK分析软件建立其整车的动力学模型,得到其性能参数,为以后再创新建立数据依据。
The CRH3 EMU is the fastest running motor vehicle currently in China. Its drive unit adopts frame suspension, which is different from other common shaft suspension and body suspension types. Traction motor is one of the important components of the power steering drive. Siemens Motor Corporation has installed the motor of the CRH3 type with a leaf spring structure suspended on the frame, which not only can bear the weight of the motor, but also weaken the traction motor brought by the traction motor Shook his head inertia. The cleverness of this structure design is self-evident. In this paper, Solid Works software will be used to build a 3-D model with CRH3 type motorcar bogie. Then the dynamic model of the whole vehicle will be set up by SIMPACK software to get its performance parameters and establish the data basis for further innovation.
