Abstract

Three-dimensional finite element (FE) models were developed to study the effect of holes with different shape on bolted connectors´ fatigue life. Using MSC.Patran commercial finite element analysis software to create models. Using Nastran´s nonlinear contact algorithm to do the FEM simulation, and the MSC. Fatigue was used to analyze the fatigue life. In the analysis, the material properties, contact relationship between bolts and aluminous plate, aluminous plate and aluminous plate were considered. The effect of bolt holes with different shape on bolted connectors´ fatigue life has been analyzed by comparing the results. The results of this study can provide reference for the design of bolted connection in aircraft and vehicle structures. And it is useful for failure prevention.
