摘　　要：研究压电智能梁结构力电耦合位移电势分析的新理论新方法.首先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.其次与经典理论解和通用有限元软件ANSYS的结果进行比较说明了本文研究方法的正确性和合理性.然后针对不同边界情况和不同荷载形式进行分析,最后用大量图表显示了本文研究结果.The new theory and new method of the electromechanical displacement and electric potential analysis of piezoelectric intelligent beam are studied in the paper. Firstly, based on intelligent constitutive relation theory, instantaneous variational principle and spline dispersing, the analysis equation of the displacement and electric potential of the piezoelectric intelligent beam is established by the intelligent sline finite-point method. Secondly, comparing with the theoretical solution and the results of ANSYS indicates the correctness and rationality of the present. Then, the different boundary＇conditions and different load formals are discussed in the paper. Lastly, the results are given with a lot of schematics.
