摘要：

振动离心机是地震研究和飞行器离心振动复合环境试验研究的重要工具，顺臂振动是其重要的运行工况，而顺臂隔振是振动离心机在该工况下稳定运行的关键。在分析振动离心机顺臂振动工况的基础上，利用空气弹簧的动刚度小而轴向承载力大等特点，设计了一种安装于振动离心机转臂上可测不平衡力的顺臂隔振系统。基于隔振系统的力学模型，通过解析简化获得该系统的力传递率解析方程，并分析了影响该系统隔振能力的主要因素。针对某振动离心机，利用解析方程计算了其隔振系统的力传递率，并通过隔振系统力学模型对其传递力进行了仿真分析，理论计算及仿真所得的力传递率基本一致且均较小。结果表明：以空气弹簧为主体的顺臂隔振系统可有效隔离振动离心机的顺臂振动冲击，力传递率解析方程可用于隔振系统隔振能力评估计算。

Abstract:

Centrifugal shaker is an important tool for earthquake research and experimental study on the centrifugal vibration compound environment of aircraft. Vibration along the swing arm of centrifugal shaker is an important operation condition, while the vibration isolation along the swing arm has a great effect on the stable operation of centrifugal shaker in this operation condition. Based on the analysis of operating conditions of vibration along the arm, a vibration isolation system on the rotating arm of centrifugal shaker was designed by utilizing the characteristics of small dynamic stiffness, large axial load bearing capacity of air spring, in which unbalance force could be measured. Based on the mechanical model of the vibration isolation system, the analytic equation of force transmissibility of the system was obtained by the analytic simplification, and the main factors affecting the vibration isolation capability of the system were analyzed. According to a centain centrifugal shaker, the force transmissibility of the vibration isolation system was calculated by the analytical equation, and the transmission force of the vibration isolation system was simulated by the mechanical model, and the force transmissibility obtained by theoretical calculation and simulation was basically the same and small. The results indicated that the vibration isolation along the swing arm could effectively isolate the vibratory impulse of centrifugal shaker, and the force transmissibility of the vibration isolation system calculated by the analytical equation could be used to evaluate the vibration isolation capability of the vibration isolation system.
Key words: centrifugal shaker    vibration isolation    air spring    unbalance force    force transmissibility
