摘　　要：复合材料发展快速且已经广泛应用,但是由于整体制造困难等因素,结构件之间需要有大量的机械连接,因此提高连接区安全性和经济性是一个重要的课题。以复合材料壁板与钛合金接头连接结构为研究对象,开展了连接强度试验研究,测得了结构件的极限拉伸载荷与应力应变数据,得到结构件载荷传递路径以及危险螺栓位置,并与仿真结果进行了对比分析,获得了一些有意义的结果。Composite structures has been rapidly developed and broadly used in engineering field. A mount of mechanical connections are still existed in composite structures because of the difficulties of integral molding. It is urgent to improve its security and economic efficiency. Aiming at this, it analyzes the connecting structure in composite panel and titanium alloy under tension load. Connection strength experiments are detailedly executed. The maximum connection load, stress and strain, load transferring path and dangerous bolts are tested and ana- lyzed. The experimental results are compared with those simulations. Some important results are obtained and analyzed.
