Masseccentricity only influences the main critical peak and has less effect on other peaks.
质量偏心主要影响临界峰值，对其它各峰值影响很小。

The bifurcation diagrams of bending and torsional vibrations can be divided into four zones which have different influence of masseccentricity.
同时，弯振和扭振分叉图可分为四个运动区，质量偏心对这四个运动区的影响各不相同。

The results show that the coupled bending-torsional vibration range increases and the motion changes from periodic motion to quasi-periodic motion as the masseccentricity rises;
