Abstract

Groov-Pin corporation presented team Groovy-Pin with the capstone design project at the beginning of the fall semester. The capstone design project with Groov-Pin was primarily focused on the performance of the threaded inserts that the company manufactures. The company presented a plan of action to analyze the forces, torque and deformation caused through thread forming and thread failure using finite element analysis in Abaqus. The project goal was to create a model in Abaqus that would test the specific insert that Groov-Pin would like to analyze by creating a force or a torque on the fastener.

The capstone design project with Groov-Pin was primarily focused on the performance of the threaded inserts that the company manufactures. The company presented a plan of action to analyze the forces, torque and deformation caused through thread forming and thread failure using finite element analysis in Abaqus. The project goal was to create a model in Abaqus that would test the specific insert that Groov-Pin would like to analyze by creating a force or a torque on the fastener.

This semester Team Groovy-Pin was able to create a more successful pull-out test and a deformation model. The pull out test was refined so that the base material did not shear fully and instead the bolt was pulled out by only one thread pitch. In the deformation simulation, Groovy-Pin also was able to dent an insert inward successfully and show the deformation that takes place. The dented insert is used by Groov-Pin to increase prevailing torque by increasing contact between the threads of the bolt and internal threads of the insert. Groovy-Pin attempted to create a prevailing torque simulation by screwing in a bolt into the dented model but was not able to achieve acceptable results due to difficulty with modeling the complex interactions.
