| 摘 要： | 现有分析车一桥耦合振动的研究中，都假设移动车辆与路面的接触关系为点接触．事实上，轮胎与路面是通过面接触的,通过建立新的三维车轮模型，分析了面接触对车一桥耦合振动的影响,将车轮与路面的接触面简化为长方形，通过接触面间的位移协调条件和力相互作用建立车一桥耦合振动方程,同时还研究了接触面对车一桥耦合振动的影响。

| Abstract: | When establishing the equations of motion of the bridge-vehicle coupling system,most researchers simplify the contact between the vehicle tire and road surface as a point contact.In reality,a vehicle tire deforms and makes contact with the road surface over a footprint area called patch contact.This paper presents a new method that allows for the effect of the patch contact on the dynamic response of the bridge-vehicle coupling system.In this method,the vehicle tire is modeled as a three-dimensional elementary spring model,and the patch contact is assumed to be a rectangle.The numerical simulations and field test results show that the proposed method can simulate the interaction between the bridge and vehicles more rationally. |
