摘　　要：按平面应力问题 ,直接从压电物理方程出发 ,导出了压电梁的状态方程。在此基础上 ,给出了两端简支压电梁机电耦合作用在均布载荷下的精确状态方程解。算例表明 :本文结果与文献 [1]吻合相当好 ,并且很容易推广到压电层合梁的静力。The state equation of Pieoelectric beam is deduced directly from a piezoelectric physical equation in terms of a plane stress problem. The exact state equation solution of mechanical electric coupling for a simply supported beam subject to uniform distribution of load is given. Examples show that the results are good in harmony with those in the paper. This method is extended to the static, dynamic and stability analyses for a piezoelectric laminated beam.
