摘要
利用最小势能原理,建立压电体的能量泛函,并引入位移形函数,利用中性面节点的位移描述任一点的位移以及电势,将应力、应变带入泛函,得到了动力方程,进而求得位移、应变和内力,实现振动控制。
Using the minimum of weak energy principle, it establishes the energy scope of pressing electricity. Brought by motive function, it uses medium joint motive to describe the movement and electricity of each point. It also puts the stress changes into the function and gets the motive formula, in order to realize the shaking control.
