Abstract: This paper introduces the mathematical model of 12 Degrees of Freedom (DOF) light armoured vehicle, which consists of eight DOF in vertical motion of eight tyres, three DOF in vertical, roll and pitch motions of vehicle body and one DOF in angular motion of gun turret relative to weapon platform. Two sources of disturbance considered in this study are road irregularities and reaction force at the weapon platform. The results of the study show that the stability augmentation based active suspension system is able to significantly improve the dynamic performance of the light armoured vehicle compared with the passive system.
