摘要针对现有曳引机减振常采用的高分子减振垫因环境因素而引发性能大幅退化问题，本论文以电梯曳引机减振器的工程应用需求为导向，确定减振器所需阻尼元件的刚度后，采用真空渗流技术将硅橡胶填充入金属橡胶孔隙并形成包覆，研制出一款耐环境影响的高性能金属橡胶/硅橡胶连续互穿相复合减振材料（MR-SRC）。然后基于实际结构建立电梯曳引机的有限元数值模型。对加装MR-SRC减振器前后的电梯曳引机进行了模态分析，确定了整体结构的固有频率和振型。对MR-SRC减振器进行冲击响应分析，对比不同MR-SRC材料和冲击载荷对响应的影响，校核减振器的强度。接着，基于MR-SRC的近似等效，对减振器系统的冲击响应进行了理论计算，得出金属橡胶密度为1.8g/cm3的MR-SRC减振器对减振效果最佳。最后将所制备的MR-SRC减振器安装于实际电梯曳引机，按照电梯减振国标要求，测试电梯在运行过程中的加速度和速度变化，计算并校核电梯运行的相关特性参数。本论文提出的减振器为电梯安全可靠运行提供了一种新途径。

Abstract：In response to the problem of significant degradation of the performance of existing polymer damping mats used for traction machine damping due to environmental factors, this thesis is oriented to the engineering application requirements of elevator traction machine dampers, and after determining the stiffness of the damping elements required for the dampers, a high performance metal rubber/silicone rubber continuous interpenetrating phase damping material with environmental resistance is developed by filling the pores of metal rubber and forming an envelope using vacuum infiltration technology. composite vibration damping material (MR-SRC) that is resistant to environmental effects. Then the finite element numerical model of the elevator traction machine was established based on the actual structure. The modal analysis of the elevator traction machine before and after the addition of MR-SRC damper was carried out to determine the inherent frequency and vibration pattern of the overall structure. The impact response of the MR-SRC damper was analyzed to compare the effects of different MR-SRC materials and impact loads on the response, and the strength of the damper was calibrated. Then, based on the approximate equivalence of MR-SRC, the impact response of the damper system was theoretically calculated, and it was concluded that the MR-SRC damper with a metal-rubber density of 1.8 g/cm3 has the best effect on damping. Finally, the prepared MR-SRC shock absorber is installed in the actual elevator traction machine, and the acceleration and velocity changes of the elevator during operation are tested according to the requirements of the elevator vibration damping national standard, and the relevant characteristic parameters of the elevator operation are calculated and checked. The dampers proposed in this thesis provide a new way for safe and reliable operation of elevators.
