Abstract

This paper proposes the 3D modeling and simulation technique for predicting the integrated performanceof combat vehicle. To consider the practical driving and firing condition of a combatvehicle, the full vehicle model, which can define the six degrees-of-freedom of vehicle motionand various firing angles, is developed. The critical design parameters such as the stiffness anddamping coefficient of suspension system are applied to construct the analysis model of vehicle. A simple ballistic model, which incorporates the empirical interior ballistic model and thepoint mass trajectory model, is built to estimate the firing range and the firing recoil force. Topredict the integrated performance and analyze the effect of system parameters, MATLAB/SIMULINKmodel of a combat vehicle for performing the real time simulation is also developed. Several simulation tests incorporating the road bump and the firing recoil force are presented toconfirm the effectiveness of the proposed vehicle model.
