摘要
研究面导纳在结构之间接触表面上振动能量传递时的特性，并利用复功率方法和振强的概念推导出无限大薄板的矩形而导纳在均布力作用下的解析表达式，为分析结构间接触表面上能量传递提供了理论工具．根据理论计算结果，研究并描述了接触面积的大小、边长和矩形面积的长宽比等参数对能量传递的影响，为研究隔振问题提供了有效的理论依据和方法．
This paper investigates the characteristics of surface mobility when power transmission over the contact area between sub-structures is considered. An analytical formula of the surface mobility of an infinite homogeneousplate over a rectangular contact area subject to a uniform, conphase force excitation is derived by using complex power method and the concept of structural intensity. This formula provides a theoretical tool for investigating power transmission over the contact area between sub-structures. The influences of the size, the dimension and the aspect ratio of the contact area on power transmission are analyzed and described according to the results calculated, that provides an effectively theoretical method for investigation of vibration isolation.
