摘要
随着我国工业基础的发展和提高,现阶段公路桥梁车桥动力带来的作用力问题慢慢显现,成为桥梁设计相关行业的重难点.以某车辆结构为例,从构件弹性以及阻尼性质研究入手,对汽车结构进行建模,建立一个车桥耦合振动模型,通过行车道位置、车桥质量比、桥梁模型支座形式等因素的综合分析得到耦合振动规律,从而可以为相关理论研究提供数据参考.
Abstract
With the development and improvement of our industrial base,the dynamic force of the highway bridge appears slowly at present,and it is the key difficulty of bridge design.In this paper,a vehicle structure is taken as an example,starting with the study of component elasticity and damping properties,the vehicle structure is modeled,a vehicle-bridge coupling vibration model is estab-lished,and the coupling vibration rule is obtained through the comprehensive analysis of factors such as lane location,vehicle-bridge mass ratio,bridge model support form,so as to provide data reference for future theoretical research.
