摘 要: | 根据哈密顿原理,提出了应用插值振型函数法,研究多跨连续梁在移动荷载作用下车桥耦合振动的动态响应问题。在具体的算例中,给出了三跨等截面连续梁在不同速度的移动荷载作用下的数值结果。算例分析表明,该方法具有很好的收敛性和很高的精度。

Abstract: | According to Hamilton Principle, the interpolating vibration mode function is proposed to study the dynamic response of vehicle-bridge coupling Vibration under the moving load. In an detailed example, the data result of three-span equal section continuous beam under the moving load at different speeds is given. The analysis shows that the method has good convergency and high precision. |
