| 摘 要： | 研究了由硬性的Timoshenko梁连接组成的桁架结构的振动。有限元方法可以处理任意配置结构，而数值解析适用处理移动荷载。两者结合后的数值模拟表明，动态响应速度比相应的静态响应速度高，动态接触力可以比静态值高很多。

| Abstract: | The vibration of a truss structure composed of rigidly connected Timoshenko beams is studied .The FE method is used to deal the arbitrary configuration structures while the numerical-analytical method to the moving loads . The simulation based on the above two combined method indicate that the dynamic response is faster than that of the static w hile the dynamic contact force is much higher that that of the static . |
