Automotive crash test: How to solve the problem of measuring tension load – Force Sensing bolts, an innovative solution.
Sensor Solutions was approached with a problem of measuring tension load in a batch of miniature bolts for an automotive crash test.
A small hole was drilled into each of the bolts and a full bridge measuring axial load was installed. The bolts were then individually calibrated in increments of tension up to 7 tonnes.
The bolts yielded some interesting data for the engineers and the bolts survived the test so could be used again for subsequent testing.
