摘要
对重物提升过程的等刚度和变刚度两种动力学模型进行动力学模拟分析。通过比较两种模型下重物的位移和钢丝绳动载荷变化过程,得出两种模型的特点和选用原则,对正确地选用分析模型具有借鉴意义。
Two mechanical models, unchangeable stiffness system and changeable stiffness system, have been simulated and analysed in this paper. Through comparing displacement and dynamic load changing of steel cable in two mechanical models, it is resulted in their characteristics and selection rifles, and it is helpful to select analysis model correctly.
