A new type electrohydraulic servo valve based on magnetic shape memory alloy

摘要：

　　In this paper, the magnetically controlled characteristic and shape variation mechanism magnetic shape memory alloys (MSMA) sample are studied through the servo valve actuator based on the MSMA.The MSMA is a new type of functional materials, which has huge driving force and large controllability displacement.The kind of actuator is designed by differential mode of MSMA, employing bias coils to generate biasing magnetic field and applying field coils to provide magnetic field which is controllable.The relationship between displacement of the new actuator and time is got by numerical simulation using Maxwell software.Finally, motivated by the simulation results, the rationality of structural design of the new type of actuator is validated.
