Abstract

Abstract:

In view of the ballpoint pen tip fracture damages emerged during the assembly process of certain type of ballpoint pen equipment, 3D model of the ballpoint pen tip and the corresponding assembly equipment was constructed by Pro/Engineer,and process stress was analyzed by means of finite element analysis software ANSYS.The forces and failure patterns during various stages of assembly were acquired by means of data collect system, then the process stress was analyzed by means of finite element analysis software ANSYS,finding the maximum stress and stress concentration position.Furthermore,the related experiment was carried out to demonstrate the validity of the finite element analysis,then the reasons for damage of ballpoint pen head were found out, finally feasible solutions were put forward.

Key words: ballpoint pen, threaded connection, finite element analysis, solutions, stress research
