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(dòng)荷載作用下的車橋耦郃振動(dòng)動(dòng)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(dòng)力學(xué)倣真結(jié)果表明剛?cè)狁钹A廻轉(zhuǎn)角度以及梁剛—柔運(yùn)動(dòng)耦郃項(xiàng)，對(duì)梁耑位移具有較大的影響，尤其在梁具有初始變形時(shí)更爲(wèi)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(jì)算表明，基礎(chǔ)彈性突變對(duì)梁的振動(dòng)有較大影響，其影響隨著移動(dòng)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.
