摘要
固有频率是物体的重要参数,本文介绍了使用虚位移原理来求解物体固有频率的方法。根据物体的受力条件和边界条件利用虚位移原理求出物体的变形能,根据能量守恒的原理计算出物体的固有频率。
The natural frequency is important parameter to rigid body.This article introduced the method of using the virtual displacement principle to solve the object natural frequency.Using the virtual displacement principle according to the object stress condition and the boundary condition to extract the object the energy of deformation,it calculates the object＇s the natural frequency according to conservation of energy＇s principle.
