摘要
介绍了利用作为动力吸振器(DVA)的弹性体的弹性变形,减小对乘坐品质有重大影响的车体弯曲振动的研究。车辆振动试验结果表明,可以同时减小车体2个不同的弯曲振动模态,证实了通过采用圆环状弹性体可达到多模态降低的效果。
The research on the reduction of flexural vibration of rail vehicle carbody which has large lint）act on ride comfort is described utilizing elastic deformation of an elastic body as the dynamic vibration absorber. The vehicle vibration test result shows that the two different flexural vibration modes can be reduced simuhaneuusly, and the multi-modal reduction effect by the elastic torus has been confirmed.
