摘　　要：研究了压电智能梁力电耦合应力应变分析的新理论新方法.采用智能样条有限点法,从位移模式出发,以智能本构关系、瞬时变分原理以及样条离散化为基础建立了压电智能梁力电耦合性能分析的计算模式.针对不同边界情况和不同荷载形式进行分析,并与通用有限元软件AN-SYS的结果进行比较,结果表明本文方法简单有效,具有令人满意的精度.The new theory and new method of the electromechanical stress and strain analysis of piezoelectric intelligent beam are studied. Based on intelligent constitutive relation theory, instantaneous variational principle and spline dispersing, the analysis equation of the displacement and electric potential of the piezoelectric intelli- gent beam is established by the intelligent spline finite-point method. Comparing with the results of ANSYS in- dicates the correctness and rationality of the present. Different boundary conditions and different load formals are discussed. The results are given with a lot of schematics.
