基于SolidWorks Motion的曲轴动平衡仿真

Dynamic Balance Simulation for Crankshaft Based on SolidWorks Motion

利用SolidWorks建立压缩机三维模型,并在Motion模块下模拟曲轴动平衡仿真,结合双面平衡法使曲轴达动平衡,使其符合国际标准ISO1940中规定的刚性转子的平衡精度要求。这种方法可以在曲轴设计前期就可以对曲轴进行动平衡分析,提高曲轴设计精度、缩短曲轴开发时间、降低开发成本,本文将结合实例进行具体阐述动平衡原理、方法、用途及应用范围。

The compressor′s 3D model is established by SolidWorks, and the dynamic balance of crankshaft is simulated under the Motion module. The crankshaft achieved dynamic balance using two-plane balancing method, which mects the requirements of the rigid rotor balance precision specified in the international standard ISO1940. This method can be used to analyze the crankshaft dynamic balance in the early stage of the crankshaft design, improve the crankshaft design accuracy, shorten the crankshaft development time and reduce the development cost. This paper will elaborate the principle, method and application scope of the dynamic balance combined with actual examples.
