beam vibration

基本解釋

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.
根據(jù)哈密頓原理，應(yīng)用插值振型函數(shù)法，分析了多跨連續(xù)梁在移動荷載作用下的車橋耦合振動動態(tài)響應(yīng)。
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.
動力學(xué)仿真結(jié)果表明剛?cè)狁詈匣剞D(zhuǎn)角度以及梁剛—柔運動耦合項，對梁端位移具有較大的影響，尤其在梁具有初始變形時更為明顯。
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.
計算表明，基礎(chǔ)彈性突變對梁的振動有較大影響，其影響隨著移動荷載速度的增加而增加。

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.
