摘要
建立了液压电梯轿厢的振动模型。考虑了系统振动时橡胶减振垫的作用，合理选择了电梯运行的速度曲线。在电梯运行速度曲线下．采用不同刚性、不同阻尼的减振垫结构。对轿厢振动系统进行仿真研究。结果表明：在合理选用减振垫的前提下．适当增加减振垫的弹性刚度可以减弱轿厢的振动位移，增加阻尼可降低轿厢的振动加速度。从而减小了轿厢的振动。
Considering the effect of rubber damping pad and reasonable choice of the speed curve of elevator running, the vibration model of hydraulic elevator is established. Under the speed curve of elevator running, using the cushioning structure of different rigidity and damping, the simulation study on the car vibration system is launched. The results show that on the premise of reasonable selection of damping pad, appropriate increase of elastic stiffness of damping pad can weaken vibration displacement of the car, the vibration acceleration of the car reducing as the damping increased. In this way, it helps to reduce the vibration of car.
