摘要:

针对圆珠笔装配中出现笔头断裂破损的情况,运用Pro/Engineer建立了圆珠笔头及其装配设备的3D模型,并通过有限元软件ANSYS对其进行分析。利用数据采集系统采集笔头在装配各个阶段的受载,再通过ANSYS对其进行应力分析,找出最大应力和应力集中位置,并进行相关的实验,验证了有限元分析的正确性,得出了笔头破坏的原因,最终提出了具有可行性的解决方案。

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
