摘　　要：针对采用传统滚动导靴(含弹簧与橡胶阻尼)存在着振动抑制能力有限的问题、采用主动控制滚动导靴的控制复杂与高成本的问题,提出一种液压阻尼被动控制的滚动导靴减振方法,在满足高速电梯的减振需求的同时又能大幅度降低振动控制的成本。首先对高速电梯水平振动的原因以及振动评价标准进行分析;通过一种液压作动器 + 液压阻尼代替传统的减振弹簧和橡胶阻尼,形成一种新型的弹簧–阻尼系统,进而起到对电梯横向振动进行减振的作用;建立传统滚动导靴模型为对照组,进行AMESim仿真,探究液压被动导靴的性能。最终得到,本文设计的液压被动导靴在减振方面已达到优等品。Aiming at the problem of limited vibration suppression ability using traditional rolling guide shoes (including spring and rubber damping), and the complex and high cost of controlling active control rolling guide shoes, a hydraulic damping passive control rolling guide shoe damping method is proposed, which can greatly reduce the cost of vibration control while meeting the vibration ab-sorption needs of high-speed elevators. Firstly, the causes of horizontal vibration of high- speed el-evators and the vibration evaluation criteria are analyzed. Through a hydraulic actuator + hydraulic damping instead of the traditional damping spring and rubber damping, a new spring- damping system is formed, which then plays a role in damping the transverse vibration of the elevator;The traditional rolling guide shoe model was established as the control group, and AMESim simulation was carried out to explore the performance of the hydraulic passive guide shoe. Finally, the hydrau-lic passive guide shoes designed in this paper have reached excellent products in terms of vibration absorption.
