摘　　要：针对复杂振动控制中需要摩擦阻尼器输出不同阻尼力的需求,设计了一种反馈控制摩擦阻尼器。该类阻尼器可以利用被控结构振动位移信号进行阻尼力调整,从而实现振动半主动控制。通过阻尼器工作能力理论计算和仿真分析,对影响新型阻尼器性能的参数进行研究。利用有限元仿真分析方法对活塞体等关键部件进行结构分析,验证该结构的合理性和安全性。最后建立起了反馈控制摩擦阻尼器的数学模型,并得出其力-位移滞回曲线。To meet the vibration control needs of working on varied vibration conditions, a new type of feedback controlled friction damper was developed in this research, which was controlled by the feedback amplitude signal of the controlled vibration structure. By calculation and analysis of its work capacity, the parameters of the feedback controlled friction damper were determined. The reasonableness and safety of the piston structure was studied using FEA. The research showed the mathematical model of its damping force and damping force-displacement hysteresis curve.
