摘要
将电梯振动系统看成两个单自由度子系统的组成,求解子系统振动的激励频率和固有频率,这是分析电梯振动较为传统的方法。现从多自由度系统的角度,提出较为全面的电梯振动模型,并求出模型固有频率的计算公式;分别用这两种方法通过实例求解系统固有频率,并作比较。
The traditional analyzing way of the vibration system about and the natural frequency of each system into two subsystems, and solving energizing frequenCY is presented,and the natural frequency subsystem. In this paper,a new multiple-degree-of-freedom model of the model is solved. Then two ways are used to solve the natural frequency for one example and the results are compared.
