摘要
本文借助阶跃函数,建立折板的壳面方程,然后应用板壳振动理论和Navier方法,求得简支折板受迫谐振的响应。由此还可求得折板自由振动的频率方程。最后利用叠加原理给出了四边固定折步谐振响应的计算公式。
In this paper, the surface equation of folded plate is established by virtue of the step function.The response of forced vibration of simple folded plate is obtained by the vibration theory of plate and shell and using the Navier method. Also, the free vibration frequency equation is therefore obtained. Finally, the response formula of folded plate with four fast edges is given in light of the principle of superposition.
