摘要
借助阶梯函数,建立了含有任意分布的用作执行器的压电片的梁横向振动方程,并利用模态法,进行了梁的振动控制研究。仿真结果表明,无论对自由振动还是受迫振动,控制效果都十分明显。
By applying heaviside function,the vibration equation governing the beam that possesses spatially distributed piezoelectric patches has been established.Based on this equation and using the modal method,some problems about the vibration control have been discussed.Numerical examples have been presented to illustrate the efficacy of the control to both free and forced vibration.
