主轴弹性对摩擦提升系统纵向振动特性影响的研究

摘要

According to the structural features of the friction hoist with high speed and heavy load,the five degree-of-freedom longitudinal vibration model with elastic main axle of friction hoist system is established with reasonable simplification,and the model of a friction hoist is analyzed by numerical simulation.The results are compared with those of the traditional 4 degree of freedom model,the elastic effect of main axle on the design results is obtained.%根据高速重载摩擦提升机结构的特点,在合理简化的基础上,建立了主轴为弹性构件的摩擦提升机5自由度纵向振动动力学模型,并结合摩擦提升机的设计参数进行了仿真.通过与传统的4自由度系统计算结果进行对比的方法,得到了在设计高速重载摩擦提升机时,主轴弹性对设计结果的影响.
