通过模拟复合材料多钉连接试验,采用ABAQUS建立有限元模型,提出3种计算复合材料多钉连接孔周应力场的数值模拟方法.结果表明,简化接触法与实验值的误差较大,插补法和准静态分析法与实验值的误差相对较小并得出复合材料多钉连接孔周应力分布情况.%Based on the composite material multi-fastener joint test in the literature, this paper proposes three kinds of numerical simulation methods for calculating the hole-edge stress field of composite material multi-fastener joint by carrying out finite element analysis in ABAQUS.Through calculation and analysis, the result proves that the error of simplified contact method is larger compared with the experimental value;and the interpolation method and quasi static analysis method have relatively small error and the hole-edge stress distribution of composite material multi-fastener joint can be obtained by the two methods.
