摘要
将全身CT机的机械回转系统简化成一个刚性转子系统,该系统的静子与支承之间存在间隙。首先对其非线性振动响应进行了解析分析,然后用数值方法研究了间隙、偏心和回转角速度等参数变化所导致的系统分岔和混沌运动的特征。
The rotating system of CT machine is simplified into a rigid rotor system. There exist clearances between the stator and the elastic support. The nonlinear vibration is analyzed analytically first. With the numerical method, the bifurcation behaviors and chaos are studied with such parameters as clearance, eccentric and rotating velocity.
