摘　　要：隔振系统具有降低振动冲击对惯性仪器影响的重要作用。本文给出干摩擦阻尼隔振系统响应的精确计算方法,并推算出系统响应具有无穷共振峰的参数条件,从而求得系统临界摩擦参数η_(r)=π/4。所得结论有助于干摩擦阻尼隔振器的设计。Isolation system has an important effect upon protecting the inertial in- strument from vibration and shock. This paper gives out an exact solution for the response of the coulomb damping system. In this paper the critical damping parameter of the unbounded resonance is also considered and will be noted by η_(cr)π/4. The conclusion will be helpful to the design of the coulomb damping isolator.
