摘　　要：针对EPGC204复合材料螺栓连接时基体开裂问题,运用数值模拟有限元仿真计算的方法,建立EPGC204零件螺栓连接时几何参数(宽径比W/D,端径比E/D)与应力的关系曲线,研究几何参数对基体开裂的影响,寻找避免基体开裂的临界几何参数,为零件设计提供参考依据。In order to solve the matrix cracking problem during bolt connection of EPGC204 composite material,the relationship curves between the geometrical parameters(width/diameter ratio W/D,end/diameter ratio E/D)and stress were established by using the method of numerical simulation and finite element simulation calculation,and the influence of geometric parameters on matrix cracking was studied.The critical geometric parameters to avoid matrix cracking are found to provide reference for parts design.
