一、概述 桥梁动力学是结构动力学的一个分支。在结构动力学的早期发展过程中,桥梁动力学,特别是由于列车动载引起的桥梁动力学问题的研究占有相当重要的地位。 高速驶过桥梁的铁路列车的动载作用是很复杂的问题,也是最早的研究课题。各国的研究者用不同的方法来研究这个问题。一种方法是以原型试验为主要手段;另一种方法则比较重
I. Overview Bridge dynamics is a branch of structural dynamics. In the early development of structural dynamics, bridge dynamics, especially the study of bridge dynamics caused by the dynamic load of trains, occupy a very important position. The dynamic load function of railway trains driving at high speeds over bridges is a complex issue and the earliest research topic. Researchers from various countries use different methods to study this issue. One method is based on prototype testing as the main means; the other method is more important.
