悬挂在做微小扰动小船下物体运动的分析

摘要

通过求解悬挂在做微小扰动小船下物体运动方程，得到解析表达式，算例分析得到，随着小船运动周期的增加，小球在水平方向和垂直方向的运动幅值都是先增大后减小；当小船的运动周期增大到某一定值，小球在水平方向和垂直方向的运动幅值达到最大值，产生共振现象．%The analytical expression is obtained by analyzing the motional equation of object, which is hung in the boat of small perturbance. By analyzing the example, it is found that the motional amplitude of small ball along horizontal and vertical direction fist increases and then decreases with the motional period of boat. And when the motional period of boat reaches a certain value, the motional amplitude of small ball along horizontal and vertical direction is maximum, namely the resonance phenomenon is happened.
