中文摘要: |
本文首先针对含压电材料的一般结构,推导了按位移和电位移求解时的混合变分原理,在此基础上,通过对面电荷取变分,直接得到了含按电压驱动压电片层合壳的有限元方程,最后给出了利用压电片进行静变形和振动控制的仿真算例,并进行了分析。结果表明,本文建立的有限元方程准确、可靠。 |
英文摘要: |
A mixed variational principle with consideration of both the total potential energy of the structure and the electric complementary energy of the piezoelectric patches has been de- duced.The finith element equations for the laminate shell containing distributed voltage- driven piezoelectric patches have been directly obtained. Numerical examples of plates and shell have been presented to illustrate the efficacy of the algorithm. |
