摘要
就起重机常见的绕线式异步电动机驱动起升机构的机械特性构造S-函数。利用构造的S-函数作为输入激励,结合一质量一自由度简单振动模型,对起升机构的动态特性进行仿真,获得了不同输入激励时系统的位移、动载系数响应的结果并作了对比分析。
In this paper, a model has been set up and S function of input excitation is used to simulate the dynamic performance of the hoist mechanism of a crane driven by asynchronous motor. A comparison is given between different displacements and dynamical load responses obtained by different input excitations.
