利用四边固支板横向自由振动的精确解作为模态坐标,在模态空间求解了四边固支压电网络板的机电耦合动力学方程.基于对压电网络板在模拟单点激励下谐响应行为的计算分析,得到了控制其各阶共振的压电网络电路元件最优电学参数.电感电阻并联型四边固支压电网络板与四边简支压电网络板不同,其具有多个局部最优电学参数.通过分析这些最优参数对其他阶共振的影响,发现四边固支压电网络板具有多阶共振抑制效果,与电阻相比,该效果对电感更加敏感.电感电阻并联型四边固支压电网络板可以实现比电阻型四边固支压电网络板更好的单模态振动抑制效果,但同时其多模态振动抑制效果会降低. Based on the exact solution of the transverse free vibration of the four sides solid braced plates as the modal coordinates, the mechanical and electrical coupling equations of the four sides fixed piezoelectric plate are solved in the modal space. Based on the harmonic response And the optimal electrical parameters of the piezoelectric network components controlling their resonance are obtained.Compared with the four-sided simple-supported piezoelectric network board, the parallel-connected four-sided fixed-voltage piezoelectric network board has many local By analyzing the influence of these optimal parameters on the other order resonances, it is found that the quadrilateral fixed-voltage piezoelectric network plate has multi-order resonance suppression effect, which is more sensitive to inductance than the resistance. Piezoelectric network board can achieve better single-mode vibration suppression than resistive four-sided fixed-voltage piezoelectric network board, but at the same time its multi-mode vibration suppression effect will be reduced.
