摘　　要：利用ABAQUS和FRANC 3D对某厂轧机主传动系统中的十字轴进行联合仿真.使用ABAQUS并借助实测扭矩数据对十字轴进行静力学分析,得到十字轴工况下的应力云图.利用FRANC 3D在应力最大点处建立初始表面裂纹,手动设置十次裂纹扩展的深度,使用Paris公式对十字轴进行疲劳裂纹扩展的模拟分析以及寿命预测.ABAQUS and FRANC 3D were used to co-simulate the cross shaft in the main drive system of a rolling mill.The static analysis of the cross shaft was carried out using ABAQUS and the measured torque data,and the stress nephogram under the cross shaft working condition was obtained.The initial surface crack was established at the point of maximum stress using FRANC 3D,and the depth of the crack propagation was manually set ten times.The fatigue crack propagation simulation analysis and life prediction of the cross axle were carried out using Paris formula.
