摘　　要：采用缠绕技术成型的圆柱型复合材料的径向强度较低,因此复合材料轮缘的径向应力分布对飞轮转子的性能起到了重要作用。过盈装配的多环结构轮缘可以改善转子径向应力的分布。文中采用三维有限元方法分析了16000 r/min的转速下,多环结构轮缘的环数、各环厚度分布以及锥度大小和方向对轮缘径向应力分布的影响。数值模拟结果为复合材料轮缘的结构设计提供了参考。The radial strength of cylindrical composite rim made by winding technology is low,so the radial stress distribution of composite rim plays an important role in the performance of flywheel rotor.The rim with over-assembly multi-ring structure can improve the radial stress distribution of rotor.This paper uses 3D finite element method to analyze the influences of the number,the taper and the direction of rings and the thickness of each ring on the radial stress distribution of rim at the speed of 16000 r/min.The numerical simulation results provide reference for the structural design of composite rim.
