Influence of Damping Layer on Dynamic Performance of Water-lubricated Rubber Bearings
摘要
Abstract
Effects of damping layer on modal frequency and modal shape of water-lubricated rubber bearings are studied by means of finite element method in Ansys Workbench. The Pulse system is used to collect the vibration signals of the bearings. The vibration spectrum analysis method is employed to analyze the influence of the damping layer on the vibration of the water-lubricated rubber bearings. The simulation results show that comparing with non-damping bearings, the damped bearings have lower low-order natural frequencies. The test results show that for the damped bearing, there are some energy concentrations near the low-order natural frequencies, but resonance does not occur under normal operating speed (0-200 Hz). The vibration of bearing can be reduced by the damping layer, especially under high speed and high loading conditions.关键词
