Abstract:

A linear actuator having a magnetostrictive rod is magnetically energized under analog logic control in operative relation to a pair of electrically disengaged one-way locking devices, one of which is interconnected with the actuator through a stroke multiplier for high force, high speed motor drive. Two stage operation of the stroke multiplier is effected through levers angularly displaced by angular deformation of the magnetostrictive rod about a pivotal axis offset from the rod axis by means of a flexible support for such levers to avoid wear and backlash.
