摘要
介绍采用实验测试与有限元计算相结合建立车架节点刚度矩阵的新方法．为汽车车架及由薄壁杆件组成的复杂刚架的设计计算提供了一种简便有效的实验解析法．
This paper presents a new method of establishing node stiffen matrix ofthe frame of a car by combining the experiment mesurement and finite elementmethod. A simple and effective experiment analysis method is presented forcalculation the frame of a car and complex frame which is made of thin walled bar.
