摘　　要：基于线性压电理论和可压缩无粘流场运动方程 ,推导出无限长带压电圆柱体流固耦合稳态解 .由于流固耦合与力电耦合的复杂性 ,文中只考虑轴对称问题 ,研究了流固耦合智能结构在不同电压作用下位移、应力、流体压力的分布情况 ,为振动噪声控制奠定基础 .Based on the linear piezoelectric constitutive relationship and compressible and non viscous fluid dynamic equation, the steady state solution to cylindrical fluid containers with piezoelectric layers is derived. Due to the complexity of the fluid solid interaction and electric mechanical coupling, only the displacement, stress and fluid pressure of axisymmetrical fluid solid interaction intelligent structure under periodic stimulation are discussed. The results obtained are useful in studying noise control.
