摘　　要：压电变换器是仿生主动构件中的一个重要组成部分 ,是一个机电耦合的交互系统。提出了如何从多角度出发建立压电型智能结构的理论模型 ,并讨论了压电耦合机电系统各参数对压电变换器的能量转换效率的影响。压电型智能结构机电耦合模型的建立有助于解释仿生主动构件的物理实质 ,设计出性能更好、效率更高的智能结构。Piezoelectric transformer is an important part in the bionic active member and it is an interactive electromechanical-coupled system. Piezoelectric intelligent structure models are presented from various angles and the effect of parameters of the piezoelectric coupled electromechanical system on the energy conversion efficiency of piezoelectric transformer is especially discussed in this paper. The establishment of the coupled model of the piezoelectric intelligent structure is helpful to interpret the physical essence of the bionic active member and to design the intelligent structure with better performance and higher efficiency.
