Abstract

Abstract: Boundary Element M ethod is usedbrthe numerical researeh on the modificati on ofthe shape of dovetail joints.The theory and practiee of Boundary Element Method are discussed for the analysis of the contact problem with friction. A numerical analysis of dovetail joints is made,and the results are compared with that of laser-speckles measuring.By numerically ana-lysing the modified dovetail joints,the change in mechanical parameters on the contact boundary is disclosed,and is in agreement with the test results.

Key words: connections, numerical analysis, boundary element method, stress concentration, fretting
