基于MSMA材料制成的气动阀的特性(中文2800字,英文2100字)
磁性形状记忆合金（MSMAs）有较大的形变范围，强度和频率，使它们适合应用在机电传感器，用于控制气动阀门。可以设计一个快速反映的机电传感器，其驱动原件不执行任何动作，当阀门使用的时候，其形状发生形变。 利用MSMA制作的构件的有效变形，运动阀门发生位置改变，从而改变流量孔板。使用MSMA制作的阀门可以成为一个新型的电动阀门，具有改进的动态运动部件，更好地抵抗外部震动性能。

Characterization of MSMA-based Pneumatic Valves
The deformation range, forces and frequency of the Magnetic Shape Memory Alloys (MSMAs) render them suitable for applications in electro-mechanical transducers, used to control pneumatic valves. A fast-operating electro-mechanical transducers can be designed, whose driving elements should not execute any motion, as they do in valves available to date, and which should get deformed instead. Utilising the deformation of an element made from the MSMA, the active element of the valves may be shifted, thus changing the flow orifice. MSMA-based valves can become a new group of electric valves, featuring improved dynamic behavior and better resistance to external vibrations. Keywords: pneumatic valves, MSMA.
