Multiple Degree of Freedom Model of Giant Magnetostrictive Actuator

<p>A specific giant magnetostrictive actuator is developed for injectors in high-pressure-common-rail system. The magnetic strength, with its axial distribution unevenness considered, is determined by the driving current and axial dimension. Multiple degrees of freedom model of the specific GM...
