Wing-Fuselage Joint Connecting Structure Strength Analysis Based on ABAQUS Contact Arithmetic
The whole aircraft calculation module normally adopts fasteners with the rod el-ement or the rigid element to simulate the joint connection structure,this simulating method may result in the over hardness of the support rigidity of the structure and cause the distor-tion of calculation result at connecting portion.The elastoplastic finite element module of wing-fuselage joint connecting structure setup on the basis of ABAQUS software accomplish the nonlinear coupling analysis and compare the calculation results and test results to verify the accuracy of simulation analysis.
