A constant flux magnetostrictive impact sensor is presented along with a discussion of prior applications and previous work on modeling of magnetostrictive sensors. A constant flux magnetostrictive impact sensor, which uses a permanent magnet, is modeled and the system in which it operates is overviewed. A detailed analytical model of the operation of the constant flux magnetostrictive impact sensor is developed. Prototype sensors were tested in both dynamic gap and magnetostrictive modes of operation. The model is validated through comparison of modeling and experimental results.
