Design of a linear electromechanical actuator with an active vehicle suspension system.

This paper presents issues in designing an electromechanical actuator-a reluctance inductor linear motor (RILM), which can be used as a shock absorber in the active suspension of electric and hybrid vehicles. A method for design calculation of tubular-form RILM module for an automotive suspension is proposed. For the proposed design, formulas that determine the geometric parameters are selected for the armature form, dimensions of the air gap, motor step, and winding parameters. The developed module of the electromechanical actuator has a form factor of a solenoid with an open magnetic system without a stopper. On this basis, selection and determination of the geometric dimensions of the module elements are determined operating under quasi-optimal ratios of basic dimensions in the magnetic core. The choice of high supply voltage is substantiated. In order to test and perfect the presented design methodology, the designed module is simulated with numerical calculation methods of the magnetic field and special calculation models. Results of calculations and simulations showed good qualitative and quantitative agreement. A module design with a smooth heterogeneous armature is selected as a result of the simulation.
