sms2.0 - smart magnetic shape memory valves
Research Task/Objectives
The increasing requirements on fast switching pneumatic valves, with respect to
functionality, installation size, durability and response time, demand for innovative valve systems. Therefore, actuators based on magnetic shape memory alloys (MSM), which can be mechanically or magnetically activated to provide stroke and force, represent an interesting alternative to conventional electromagnetic actuators due to their improved material characteristics during the last decade of research. Thus, the aim of the project is the development of a competitive fast switching pneumatic valve based on a MSM-actuator.
Approach/Results
An important aspect of the project is the collaboration of eight partners of industry and science, contributed in all steps of the value chain. The subproject of the chair “Antriebs- und Ventiltechnik” covers the development of the valve including the process from the
conceptual design to the construction of a functional design of the valve. This requires a precise adaption of the magnetic circuit and the fluid stage on the hysteretic behavior of the MSM material, which can be achieved by the use of different numeric simulation tools like FEM, Network modelling and CFD.
