有限板结构的面导纳

The surface mobility of finite plate structure

为了恰当表述面接触安装方式下的振能传递,本文介绍了面导纳的概念,针对更能反映实际基座结 构的有限薄板模型推导出面导纳计算方法,对简支和钳制矩形薄板叙述了具体过程并进行了数值计算,比较了边界 条件等设计参数对其的影响。

In order to express the vibration transfer under the surface contact area, the concept of surface mobility is introduced in this article, the calculated method of surface mobility of finite thin plate model is deduced, the numerical calculation of rectangle thin plate under two typical different boundary condition, simple-supported and clamp-supported, is carried out. At last, a discuss of different design parameter is made.
