摘要
利用胞参考点映射法对两自由度(四维)分段光滑的转子/定子碰摩模型的全局响应特性进行了计算,着重对解析分析得到的碰摩系统典型的吸引子共存现象进行了验证,确定了相应吸引子的吸引域.此外,通过计算转子/定子碰摩系统全局特性随系统参数变化的演化特点,考察了吸引子与其吸引域边界对参数变化的敏感性,讨论了其对实际转子/定子碰摩系统响应的含义.
The method of Point Mapping under Cell Reference was used to compute the global response charac- teristics of a pieeewise-smooth rotor-to-stator contact system in order to verify the theoretical analytical results, particularly computing the coexistence of attractors and their basins of attraction. In addition, the sensitivity of the system parameters on the boundaries of the basins of attraction is examined and its meaning for the responses of actual rotor/stator contact systems is discussed.
