Applications of magnetostrictive and magnetorheological materials in modern car industry and future trends

Abstract

Magnetostrictive and magnetorheological materials are becoming more widespread due to their unique properties, especially within the automotive industry. This research investigates the applications of MS and MR materials in the car industry, their limitations, and possible future trends. Literature review, expert interviews, and industry reports have been used to acquire data, while the validity of the results was ensured using triangulation. Results indicate that there are many applications of magnetostrictive and magnetorheological materials, already implemented or just being researched at the moment, from actuators and sensors to injectors and bumpers, controlled with the magnetic field. Even considering several limitations such as high price point or a need for special techniques, for example, to prevent the in-use-thickening of MR fluids, identified trends are positive, especially in terms of the development of new materials and integration of those into vehicle components.
