飞越曳引式客梯水平方向的振动分析

Vibration Analysis on Horizontal Direction of Flying Traction Passenger Elevator

通过牛顿第二运动定律创建了水平8自由度振动动力学模型,着重考查导轨刚度变化及导靴接触变形的影响,并采用MATLAB软件对所创建的模型进行模态分析。通过对导轨弯曲的分析,得出导轨异向、同向弯曲都会加剧轿厢的水平振动,且同向弯曲的影响要大于异向弯曲的结论。

Through the Newton second law of motion,a horizontal 8 degree of freedom vibration dynamic model is established.Emphasis is laid on examining the influence of the rigidity change of the guide rail and the contact deformation of the guide shoe.The modal analysis of the model is carried out by using MATLAB software.Through the analysis of the bending of the guide rail,it is concluded that the opposite direction bending and the same direction bending of the guide rail will aggravate the horizontal vibration of the car,and the influence of the same direction bending is greater than that of the opposite direction bending.
