Magnetorheological Semi-Active Suspension System for a Tracked Vehicle

Abstract:

A semi-active suspension system is researched for a heavy tracked vehicle to improve its suspension performance. This is achieved through a vane magnetorheological damper (VMRD) with special magnetic circuit which may attenuate the leak of MRF from assembly gap. A innovative strategy named frequency domain control (FDC) is proposed based on a conclusion that, in the frequency domain,the influence of damping coefficient to transmissibility for different suspension performance indicators is in good consistency. FDC only requires accelerometers mounted on sprung mass, meaning low price and high reliability that the tracked vehicle requires. The experiment indicates the designed semi-active suspension system based on VMRFD has an excellent vibration suppressing ability.
