一、前言在汽车的一些总成和部件上,常常看到通过铆钉、螺栓或焊点将一块板与结构板连接起来,使它们重叠起来,故称“重叠板”。本文以两薄板的重叠为例,说明使用有限元程序时,确立重叠板力学模型的方法。文中所建立的 I. Preface It is often seen on some assemblies and parts of a car that a plate and a structural plate are connected by rivets, bolts or solder joints so that they overlap and are therefore referred to as “overlap plates.” In this paper, the overlap of two thin plates is taken as an example to illustrate the method of establishing the mechanical model of the overlapped plate when the finite element program is used.
