beam vibration

基本解释

Based on Hamiton's principle, the coupling vibration of multi-span uniform beam subjected to moving load is analysed by using fitting beam vibration mode functions assumed modes.
根据哈密顿原理，应用插值振型函数法，分析了多跨连续梁在移动荷载作用下的车桥耦合振动动态响应。
The dynamical simulation shows that the terms of rigid-flexible motion and rigid rotating angle motion have deep influence upon the beam vibration, especially, with initial deformation.
动力学仿真结果表明刚柔耦合回转角度以及梁刚—柔运动耦合项，对梁端位移具有较大的影响，尤其在梁具有初始变形时更为明显。
The computations show that the foundation elasticity stiffness abrupt change has greater influences on beam vibration. This influences increase with increase of the velocity of the moving loads.
计算表明，基础弹性突变对梁的振动有较大影响，其影响随着移动荷载速度的增加而增加。

When sound waves enter the tube, the vibration of the droplets will cause the sensor to detect changes optically as the beam is disturbed, supposedly resulting in near-perfect vocal reproduction.
