Abstract

Mobility such as the maximum acceleration and the maximum vehicle ramp slope is important factor for estimating the integrated performance of combat vehicle. This paper proposes the mobility analysis model of the combat vehicle and the simulation technique by using design parameters of the powertrain system. To consider the practical driving condition of a combat vehicle, the in-wheel motor component with torque-speed characteristics and driveline system apply to construct the vehicle analysis model. A 3 dimensional full car model that incorporates rotational degrees of freedom of each wheel is used to predict the dynamic performances of the combat vehicle. Several simulation tests with various road profiles will be performed to obtain the driving performance indices of the combat vehicle and to verify the effectiveness of the proposed model.
