Optimization of magnetic suspension using response surface methodology

Hydraulic system of commercial vehicle is switched electromechanical system for development of next generation vehicle recently. For example electric steering system and electric break system. This paper proposes the structural of magnetic suspension for next generation vehicle and deals with optimization of geometry of magnetic suspension. Two main characteristics are required in design of magnetic suspension. Firstly, magnetic motive force (MMF) by armature winding should have linearity. Secondly, identical magnitude of output force should be produced as direction of MMF for easily control. In this paper, axis-symmetric finite element analysis is used for analysis of magnetic field analysis. In order to optimize magnetic suspension, response surface methodology combined with experimental design is applied to investigate the characteristics and optimize the magnetic suspension.
