Automated Test Equipment for the 1MT-172 Piston Actuator
Abstract
An automated tester for the 1MT-172 piston actuator has been developed. The actuator is an electroexplosive device that, when electrically initiated, extends a piston. This actuator is used in several safety and arming devices developed by the Army. The project was funded by Manufacturing Testing Technology funds and sponsored by the Army Materials and Mechanics Research Center. The output of the automated tester is the piston-force-versus- displacement curve for the actuator. This tester also makes accept/reject decisions based on peak force values and computes the total energy output. A hard-copy record is available from a self-contained plotter. As a result of this project, actuator samples can now be evaluated more rapidly and more accurately than previously possible. Screening of production samples can be made with a much higher degree of precision and confidence. This screening will yield a decreased risk of fuze failures due to poor actuator performance and thus provide potential savings of many times the project's cost. In addition, the new test technique yields design and performance information, not otherwise obtainable, of significant value to the development effort or new fuze systems.
