摘要： Apparatus and method for precisely controlling the movement of a magnetostrictive transducer including an elongated magnetostrictive rod, means for inducing a magnetic field in the rod and supplying drive current for moving the rod in response to the drive current. A temperature compensated strain sensor configuration on the rod detects the amount of rod movement in response to the drive current and provides an output signal proportionate thereto. Feedback control means coupled between the strain sensor and the current driver respond to the strain sensor output signal and vary the drive current until the strain sensor output signal matches the voltage reference set point developing the drive current.

摘要： This invention is a magnetostriction transducer (26) including a plurality of magnetostriction laminates (28) each having a first end (30) and a second end (32). The first (30), and second (32) ends of the laminates (28) include openings (38, 40). The laminates (28) are arranged in a stacked configuration, bonded together by solder (34, 36) at the first (30), and second (32) ends. At the first (30), and second ends (32) the solder extends through the openings (34, 38) of the laminates (28) forming a solder bar (34, 36) therein. The solder bars (34, 36) bond the laminates (28) together with increased mechanical strength, and also provide increased electrical contact between the laminates (28).

摘要： A method of minimizing the cold start delay and impact fatigue of an actuator includes calibrating the actuator by initially raising the temperature to a desired operating temperature through induction heating of the actuator rod. Additionally, a control system for a magnetostrictive actuator includes a rod of magnetostrictive material, a solenoid coil wrapped at least once around said rod, and a controller operatively connected to said solenoid coil wherein the controller detects an impact of the rod with another surface and adjusts the operation of the actuator to minimize the potential for additional future impacts. The rod may be segmented and include end caps to further reduce the potential for impact fatigue.
