采用位移相关型牵引拉杆橡胶节点降低车体振动的可行性研究

介绍了具有位移相关特性牵引拉杆橡胶节点的开发,对橡胶节点进行了刚度和疲劳试验,并通过实车对其隔振效果及运行稳定性进行了一系列实验台试验和线路运行试验。结果表明,该位移相关型橡胶节点达到了设计目标且满足实际运营要求。

The Feasibility Research of Displacement-Dependent Rubber Bush for Traction Links to Reduce Carbody Vibration

The development of displacement-dependent rubber bush for traction links is described. Unit testing of the rubber bushes to check their stiffness and durability, excitation tests using a full-scale test vehicle to verify the vibration isolation performance, and running stability testing with a bogie, have been carried out. A series of running tests in field were then conducted and the effectiveness of the displacement- dependent rubber bush was confirmed under actual service condition.
