Software helps determine thread fatigue endurance

A Sensor Products product story
Edited by the Engineeringtalk editorial team Jul 17, 2000

Boltfast software allows an engineer to evaluate "what if" scenarios on a bolted joint that would otherwise only be determined after extensive analysis and testing.

Sensor Products Inc introduces Boltfast, a comprehensive bolted joint analysis software package.

This Windows-based software package aids the engineer in determining the fatigue endurance limit of a thread, the amount of embedding anticipated in the joint, and the optimal tightening torque for given friction conditions.

Boltfast allows an engineer to evaluate "what if" scenarios on a bolted joint that would otherwise only be determined after extensive analysis and testing.

The Boltfast system has three main components to analyze your bolt.

1 - The Joint Analysis program that determines whether or not a bolted joint is capable of sustaining the forces acting upon it.

2 - The Thread Analysis Program which calculates the forces necessary to strip the internal and external threads as well as fracture a fastener.

3 - The Torque Analysis Program that is specifically designed to provide a means of determining the correct tightening torque and the resulting anticipated clamp force for a threaded fastener.

This component of the system takes into consideration the different friction values between the thread and nut face together with the effect of tensile and torsional stresses.

Using Boltfast enables you to not only gain insight into any loosening problems with your bolt but also what specific design changes are needed to resolve them.
