METHOD FOR IMPROVING FINITE ELEMENT ANALYSIS MODELING OF THREADED CONNECTIONS

摘要

A method for improving finite element analysis of threaded connections includes selecting at least one thread parameter for a female connection and a corresponding male connection. In two dimensions a thread form is calculated for the female connection and the male connection based on the at least one parameter. In two dimensions a geometry is calculated of the female connection and the male connection based on the thread form. In two dimensions the female connection and the male connection are segmented into predefined areas. A finite element analysis mesh is calculated based on a predetermined number of nodes for each of the predefined areas and a selected number of mesh layers for each predefined area. The two dimensional female connection and male connection are assembled. The two dimensional mesh on the assembled connections is used as input to a finite element analysis of the threaded connection in three dimensions.
