摘　　要：列车通过桥梁时产生巨大的振动,车致桥梁振动通过支座传递至桥墩,再通过桥墩传递至地基及周围环境引发环境的振动污染。采用ANSYS和UM软件建立车线桥耦合振动大系统进行车桥耦合联合仿真,计算得到与支座连接处的梁底和桥墩在分别使用普通球型支座和新型减振球型支座时的动力响应数据。结果一致表明:采用减振球型支座时桥梁上部车致振动传递至桥墩时起到明显的隔振效果。The train will make a huge vibration as it passes over a bridge. The vehicle-induced bridge vibration is transmitted to the bridge pier through the bearing, and then transmitted to the foundation and the surrounding environment through the pier and finally to cause the vibration pollution of environment. The ANSYS software and UM software are used to establish the vehicle-line-bridge coupled vibration system in order to carry out the vehicle-bridge coupling joint simulation. The calculation achieves the dynamic response data of beam bottom and pier at the connection of bearing when the ordinary ball bearing and the new vibration reduction ball bearing are respectively used. The results show that the vibration isolation effect is obvious when the vibration of the upper part of bridge is transmitted to the pier by using the vibration reduction ball bearing.
