摘　　要：为了建立精确的MFC驱动模型来分析其驱动性能,以P1型压电纤维片层合板结构为例,采用一阶剪切变形理论(简称FSDT)推导了MFC等效驱动力公式,然后将该等效驱动力作用于悬臂梁进行MFC的驱动仿真计算,并将结果与试和压电仿真结果进行对比。结果表明,在等效驱动力作用下的梁端部位移与试验以及压电仿真结果吻合度均较高。同时文中还分析了受控结构参数对MFC驱动性能的影响,总结了MFC的驱动性能与结构厚度和弹性模量的关系。In order to establish an accurate MFC driving model to analyze its driving performance,the P1 piezoelectric fiber laminate structure was taken as an example,and uses the first-order shear deformation theory(FSDT)was used to derive the MFC equivalent driving force formula,then the equivalent driving force was applied to the cantilever beam to perform MFC driving simulation calculation,and the results were compared with the test and piezoelectric simulation results.The results show that the tip displacement of beam under the effect of the equivalent driving force is in good agreement with the experimental results and the piezoelectric simulation results.At the same time,this paper also analyzes the influence of controlled structure parameters on MFC drive performance,and summarizes the relationship between MFC drive performance and structure thickness and elastic modulus.
