摘要
以某履带车辆为研究对象,基于多体动力学理论建立了履带车辆动力学模型和火炮发射动力学模型,用该仿真模型计算分析了随机路面和后坐载荷激励下车辆的动态响应.结果表明:该动力学模型及其仿真计算能够较为准确地反映履带车辆行进间的射击状态,为武器系统与底盘的匹配计算提供技术参考.
The dynamical models of tracked vehicle and gun System were developed based on multi-body dynamic theory. The dynamical response of the simulation model excited by the random road and the back load was analyzed. Simulation results indicated that the dynamical model could reflect the tracked vehicle＇s state of marching fire. The simulation results can provide technical reference for gun-chassis matching.
