摘　　要：通过仿真,研究了半主动分支电路压电可控减振技术中电感的变化对减振效果的影响,以振动能耗比例评价减振效果。仿真结果表明,分支电路电感的最优值在电路谐振时的电感值附近,而偏离电路谐振电感时,减振效果迅速下降。实验中通过测得的振动能耗比例随电感变化曲线,验证了仿真得到的结论。进一步说明了具有RL分支电路的半主动悬臂梁结构阻尼控制技术的可行性和有效性。With the emulator methods,this paper discusses the influence of variation inductance to damping erect in shock absorption by semi-active controlled piezoelectric damping with branch circuit system,and this paper use a loss factor to check the effect. The emulator result indicated that the optimum inductance is close to the number which can make the branch circuit synonymy. The experiment result shows the loss factor-inductance changing curve which verified the conclusion of the emulator. All of this explained that the structure damping control technique of RL shunted circuit is feasible and effective.
