摘　　要：对热压电仿生结构的传感器配置优化进行了研究。利用准静态热压电本构关系 ,得到了热压电仿生结构的有限元动态耦合模型 ,讨论了各耦合因素对热压电结构传感特性的影响。在此基础上 ,提出了一种热压电结构的有限元分析方法 ,并对受温度场作用的热压电结构进行了数值仿真研究 ;根据仿真计算结果分析 ,最终确定传感器的最佳布置。图 5参The sensor placement optimization in the piezothermoelectric biotic structures is studied in this paper. Using the constitutive relations of quasi-stationary piezothermoelectricity, the finite element dynamics coupling model of piezothermoelectric biotic structure is derived and the effects of coupling factors on the sensing performance of piezothermoelectric structures are discussed. Based on those analyses, a finite element analysis method of piezothermalelasticity structure is developed and the numerical simulation of piezothermoelectric structure subjected to the temperature field is presented. Utilizing the results of the optimal analyses, the optimal sensor placement is finally determined. Figs 5 and refs 8.
