## 压电智能结构接触响应的数值模拟

Title  The numerical simulation of Piezoelectric materials for Herz contact module
Abstract
Piezoelectric material has a very important position in life now. Piezoelectric materials can make voltage at both ends with the force of different sizes , then pass the signal with the voltage. Solve the contact problem of piezoelectric materials can better research the problem. And want to study of the contact point, must be applied to the Hertz contact theory. Now study is only the derivation in theory. Don't take together the results of theory and experiment.  So my topic is simulated by use of Ansys software ,the theory of numerical and experimental results are compared. Problem of two parallel columns by the distribution of deformation and force of research, experiment and the comparison of theoretical calculation. And discuss the error of the practical application of Hertz contact theory. 源自!六%维^论*文`网www.lwfree.cn
