摘要
从压电弹性介质三维本构方程及平面问题的简化物理方程出发 ,求出了悬臂压电梁在没有外加电场情况下自由端受集中力时位移、电势的解析解 ,为探索压电层的感测机理提供了参考依据。
On the basis of three-dimensional constitutive equations and their simplified equations of elastic piezoelectric materials, the analytic solution to piezoelectric cantilever beam with concentrated force at free end in terms of displacements and voltage is derived .Though the beam is not affected by any external electric field, such a solution can provide reference for probing into the sensing mechanism of piezoelectric materials.
