智能结构中压电材料厚度的设计

Thickness design of piezoelectric materials in intelligent structure

研究了在振动控制中压电元件和主结构体之间厚度的匹配关系。通过对智能复合材料的分析，得出了对称粘贴、功能不对称的压电元件所感应的有效弯矩，给出了压电元件产生最大弯矩时的最佳厚度，并讨论了材料弹性模量的影响。

This paper studied the thickness matching relationship between piezoelectric elements and main structual body in vibration control.By means of analysis on intelligent compound materials the effective bending moment induced on piezoelectric elements symmetrically pasted with asymmetric functions is obtained.The optimum thickness of piezoelectric element while producing the maximum bending moment is presented,and the influence of modulus of elasticity of materials is discussed.
