摘要
本文基于车辆 -轨道耦合大系统的思想 ,将钢轨简化为弹性点支承有限长的欧拉梁、轮轨接触关系采用弹簧接触 ,建立了轮轨动力学模型。对车轮匀速行驶过程中 ,在轨道接头压陷激励下轮轨相互作用产生垂向振动响应作了分析。并得出车速。
Considering the wheel and trac as a big coupling system,the rails as simplified Euler-beam with limit length lying on an elastic point support,and contact relation between wheel and rail as spring contact,the dynamics model of the system is established.When wheels are running at homogeneous speed,vertical vibration response of the system under excitation due to depressed track joint is investigated.The influence of the speed and the depressed degree of track joint on the magnitude of vibration is also presented.
