Stress Analysis of Threaded Connections by Finite Element Method

抄録

This paper describes a finite element analysis of elastic bodies with many contact surfaces and the applications of this method to the stress analysis of threaded connections. It is shown that the stress distribution in the threaded connections with dimensional modifications such as differential pitch and flank angle is analyzed by this method as easily and accurately as in the normal threaded connections. The stress distributions in the double nuts connection and flange coupling clamped with bolt and nut which have not been clarified previously are analyzed by this method. The results obtained confirm the utility of this method in engineering science and practice.
