摘要
本文研究了液压粘弹性控制系统（ＨｙｄｒａｕｌｉｃＶｉｓｃｏｅｌａｓｔｉｃＣｏｎｔｒｏｌＳｙｓｔｅｍ简称ＨＶＥＳ）与单自由度所构成的控制体系的频域特性，采用能量法建立了该体系阻尼比的计算方法，分析了ＨＶＥＳ各参数变化对阻尼比的影响，讨论了ＨＶＥＳ中液体耗能和粘弹性材料耗能之间的比例关系，由此揭示了ＨＶＥＳ的减振机理，从而为ＨＶＥＳ的工程应用奠定了基础．
In this paper, the frequency domain properties of control system composed of HVES (Hydraulic Viscoelastic System) and SDOF (Single Degree of Freedom ) structure are studied. The calculation method for damping ratio of the system is dveloped, and the effect of parameters of HVES on the damping ratio is discussed. Then, the ratio between the energy dissipated by liquid and that dissipated by viscoelastic material is studied. The work of this paper provides a foundation for actual application of HVES.
