摘　　要：对电梯进行动力学建模并对固有频率进行求解,在此基础上,推导出电梯各阶固有频率相对于电梯不同参数的灵敏度计算公式,得出第四阶固有频率相对于刚度参数的灵敏度变化规律,为电梯动态特性的优化提供依据。In the article,a dynamics model for the elevator system was established and the natural frequency was solved. Based on the model and the solution, it deduces the sensitivity formula between the elevator various steps natural frequency and the elevator different parameter, obtains the changing rule of sensitivity of the fourth step natural frequency as the rigidity parameter changes, and provides the basis for the elevator dynamic characteristic optimization.

关 键 词：刚度 固有频率 灵敏度
