摘要:

随着压电材料的应用越来越广泛,对压电材料的性能分析也越来越受到重视。针对功能梯度材料固有频率的分析,采用ANSYS 12.0中的Solid98 单元进行分析,在此基础上采用ANSYS中的APDL 语言进行编程,为实现参数的变化,假定材料的所有性能参数是变化且按同一方向进行变化,变化的方向为板厚方向,从而实现了压电材料性能的梯度化变化,并对其固有频率做了计算与探讨。

关键词: 功能梯度, 压电, ANSYS, 固有频率

Abstract:

With the growing application of piezoelectric materials,the characteristic analysis of piezoelectric materials is taken more and more seriously. For the natural frequency analysis of functionally graded materials,the Solid 98 element in the ANSYS 12.0 and the parameter designing of APDL language are adopted,supposing that the characteristic parameters of the material change along with the thickness of the plate. The gradient change about characteristic parameters of piezoelectric material is realized,and natural frequency of the functionally graded piezoelectric laminate is analyzed.

Key words: functionally gradient, piezoelectricity, ANSYS, natural frequency
