摘要
模拟现役不同状态下的桥梁静动载试验的过程。理论上建立车辆荷载作用的动力模型,将车辆模拟为三自由度模型,桥梁选用简支梁,并且应用有限元软件ANSYS对系统进行模拟的方法,模拟系统模型,并且模拟静载试验以及匀速跑车试验的几种工况,分析静载试验应力-应变关系以及匀速跑车试验时桥梁的动力响应。
The static and dynamic test,which is in different situation,is simulated.The vehicle loading dy-namic model is built theoretically,and the vehicle is simulated by triple free of degree model.Selects the simple supported bridge,applies finite element software ANSYS simulating the system,simulates system model,and simulates several operating model of static test and car running at constant speed test.The relationship between stress and strain in static test,and dynamical response of bridge in car running test...
