Spline Finite Point Method For Analysis Of The Pizepelectric Intellectual Plate

Considerable attention is paid to the research on piezoelectric intelligent structures in recent years. This paper set out from the high order shear deformation theory at first, and utilize the spline finite point method to set up a new dynamic model of piezoelectric intellectual plate. Secondly ,a corresponding MATLAB program is written according to the theory, and has analysed the deformation of the piezoelectric intellectual plate. In the end , this paper has analysed the vibration control of the piezoelectric intellectual plate. Some results are compared with the analytic values, and have proved the rationality of the results of this paper. The results of calculation indicate, utilizing the spline finte point method to carry on the analysis of the intellectual structure, the model is simple, the physics relation is very clear. Comparing with the finite element model, the spline finite point method has greater superiority.
