Analysis of Load-bearing Capacity of Aircraft Thin-walled Parts Damage before and after Riveting Repair
The riveting was one of the common repair methods in aircraft structure damage repair.In order to study the load-bearing capacity and failure mode of aircraft thin-walled part damage before and after riveting repair,by using ANSYS/LS-DYNA software,we established a three-dimensional finite element model,carried out the quasi-static tensile simulation,and compared the corresponding simulation results with experimental results.The results showed that finite element analy-sis could effectively simulate the load-bearing capacity and failure mode of aircraft thin-walled part damage before and after riveting repair,at the same time,we analyzed the influence of rivet arrangement and patch shape on the load-bearing capaci-ty of aircraft thin-walled part damage before and after riveting repair.These results provided a reference basis for optimizing the design of aircraft structure riveting repair process parameters.
