Design, Modeling and Simulation of an Innovation Pneumatic High Speed on-Off Valve Based on Giant Magnetostrictive Material

Abstract:

Based on giant magnetostrictive material, a new design of pneumatic high speed on-off valve is presented in this paper. To settle the problem of balancing fast response and large flow, a cantilever beam is employed as both displacement amplifier and valve spool in the innovation structure of the valve. The dynamic model of the valve is established by analyzing the dynamic performances of the giant magnetostrictive actuator and the cantilever beam, based on the theories of electromagnetism and the mechanical vibration. A simulation on this model is carried out to investigate the performance of the valve. Results of the simulation show that the new pneumatic high speed on-off valve is able to achieve the goal of high frequency response, while satisfying the requirement of a large flow.
