Abstract:

A calibrated stop bolt is provided for measuring the dynamic load transmitted to the calibrated stop bolt during a shock test. The stop bolt includes an anterior extension and a posterior extension, for restraining a torpedo bearing plate there between, and also includes a plurality of strain gauges mounted at the top portion of each extension. In one embodiment, eight strain gauges are utilized, with two strain gauges placed on each side of the two extensions, i.e., in a full bridge arrangement. The calibrated stop bolt is preferably mounted to a base plate and bolted at each end to a longitudinal test fixture. The calibrated stop bolt can be utilized with a conventional longitudinal shock test fixture, torpedo shape and heavy weight shock machine.
