摘　　要：从高阶剪切变形理论、智能本构关系、瞬时变分原理和样条离散化出发,建立了压电智能板分析的样条有限点法。对压电智能板的变形进行了分析,结果与相应的有限元解作了详细的比较,证明了本文方法的正确性。计算结果表明,利用样条有限点法进行智能结构的分析,计算模型简单,物理关系明确,与有限元法相关的计算模型相比,具有较大的优越性,实用价值高。A new method named spline finite point method for analysis of piezoelectric intellectual plate is presented in the paper, which is based on higher-order shear deformation theory, intelligent constitutive relations, transient variational principle and spline dispersing. Compared with the finite element method, the deformation of the piezoelectric intellectual plate confirms the correctness and rationality. The calculation indicates that by utilizing the spline finte point method to carry on the analysis of the intellectual structure, the model is simple and the physics relation is very clear. The spline finite point method has great superiority to the finite element model.
