摘　　要：机械设备的动力学分析应包含由于机械接口微滑动而产生的能量耗散。这就要求开发能够合理重现接口物理特性的接口动力学模型,机械接口特性的研究既可以采用精细有限元模型,也可以采用试验方法,探讨接口特性方法本身也是一个研究领域。从机械接口能量耗散机理、机械接口的动力学模型、接口动力学特性试验研究方法和接口阻尼材料4个方面评述了机械接口,特别是螺栓连接接口动力学模型的研究现状。研究现状表明,要正确理解机械接口的特性和合理建立机械接口动力学还有大量的工作要做。The structural dynamics modeling of mechanical equipment must accommodate the energy (dissipation) due to micro slip in mechanical joints. It demands the development of constitutive models for joints that adequately reproduce the features of physics. The exploration of the properties of mechanical joints-either through fine resolution finite element modeling or through experiment-constitutes in itself an area of (research). The work presented here is a review of studies on modeling the mechanical interfaces, (especially) the interface of bolted joint. The current situation of modeling the mechanical interface indicates that there is a lot of works to be done in order to correctly model the dynamic behaviors in the mechanical joint.
