摘要
本文针对车内振动问题,对压电分流电路与薄板组成的压电结构进行动力学分析,建立动力学微分方程,求解得到薄板结构的传递函数并确立目标函数;之后利用模拟退火算法,对目标函数进行优化,根据压电薄板振动幅值的变化,得到优化后的电阻值与电感值;最后,运用数值仿真计算与分析的方法,对比不同分流电路参数优化方法下的薄板振幅。通过仿真实验得出,运用模拟退火算法优化的压电薄板结构的振动幅值比极点配置法与传递函数法略小。
In this paper,the dynamic analysis of piezoelectric structure composed of piezoelectric shunt circuit and thin plate is carried out,the dynamic differential equation is established,the transfer function of thin plate structure is solved,and the objective function is established. Then,the objective function was optimized by simulated annealing algorithm. According to the variation of the vibration amplitude of the piezoelectric thin plate,the optimized resistance and inductance values were obtained. Finally,the thin plate amplitudes under different shunt circuit parameter optimization methods are compared by numerical simulation calculation and analysis. The simulation results show that the vibration amplitude of the piezoelectric thin plate optimized by the simulated annealing algorithm is slightly smaller than that by the pole assignment method and the transfer function method.
