Have you performed bolt loosening analysis on your assembly? If you haven’t done one, it could make a huge difference to its performance.
What Can Bolt Loosening Analysis Do for You?
Direct bolt tension measurement can circumvent common problems, creating better long-term results. Also, you can use this test to see which type of locking mechanism to use. That way, you don’t need to overbuild something to prevent its fasteners from coming loose.
Ultrasonic Torque-Tension Testing
Most applications don’t need torque, but it is an easier unit to measure. As a result, many designs fail to account for variances adequately. However, by using torque-tension testing, you can avoid this entirely. First, a direct line of sight between the sensor and fastener has to be established. Then, an acoustic frequency travels between them, permitting accurate measurements.
Torque-Angle Testing
Tension isn’t the only important factor, and you shouldn’t focus on it alone. For example, testing the angle of a bolt can reveal its torque. This methodology may be more effective if you’re building a thermoplastic joint. It doesn’t depend on fastener elongation, which is useful when it’s negligible.
K Factor Testing
Depending on specs, the nut factor tells you which type of finish to use on bolts. That way, if you need to use a lubricant, it’ll be obvious after testing. Most fasteners have variable friction coefficients, depending on their finishes. Plus, you must consider the material used to design them. Otherwise, it’s impossible to know whether it’ll hold under pressure.
