Multistable setups combining magnetic shape memory alloys with reluctance counterforces

Systems with the ability to hold a given position without consumption of energy, i.e. multistability, can be employed in a variety of applications. Apart from the most commonly frictionbased systems, smart materials are an option to create multistability. Here, the ability to create a multistable system from magnetic shape memory alloy (MSM) in a magnetic field, combined with a reluctance counterforce is discussed. For the approach the necessary design process is described, as well as the experimental characterization of a demonstrator system. With the multistable range of the stroke at 0.82 mm and an average resistance to disturbance of ±10 N, two key parameters of the multistable properties are determined. As an outlook, potential applications in the design of adaptable interfaces is discussed.
