摘　　要：为了研究复合材料多钉机械连接特性,对板与螺栓进行受力分析。考虑连接板对螺栓产生的弯曲效应,建立适合于复合材料连接钉载分配的有限元计算方法。并从载荷-位移曲线方面对其进行比较验证。结果表明,相比传统方法,该方法能更精确地反映复合材料连接的实际特征。采用建模方法进一步研究了板与螺栓间的弯矩随厚度变化。最后使用MSC.Pat-ran二次开发语言PCL编制相应程序,使用模块化方法实现本文数值计算方法的快速应用分析。To study multi-bolt composite joints,a numerical method is developed to simulate composite joints through detail mechanical analysis of the multi-bolt area,considering the bending effect between interface of the bolts and the laminate wall.The method is validated by comparing load-displacement characteristics to experimental results,which is proved to be more accurate than the traditional method in explaining the real mechanical characteristic of composite joints.And then,the method is used to study the effects of plate thickness on bending in composite joints.Finally,a program,using MSC.Patran secondary development language PCL,is developed to realize the numerical method more efficiently.
