摘　　要：为掌握某型轮式自行火炮行进间射击时的关键位置动态响应规律,使用Fourier逆变换法重构D级行驶路面,并利用ADAMS软件自带函数库编写发射动力学所需的复杂函数力,基于多体系统动力学和车辆地面力学,借助三维绘图软件CREO、多体动力学分析软件ADAMS、有限元软件ABAQUS建立该型装备的行走、火力、路面等部分的虚拟样机模型,通过试验验证模型的正确性,进行仿真计算并研究自行火炮2个关键位置的动态响应特征,计算结果可为研究该型装备火控系统精度、行进间射击射弹散布规律和观瞄位置干扰提供参考依据。For the purpose of mastering crucial position dynamic response law of a certain type of wheeled self-propelled gun firing on the move, D road is reconstructed based on Fourier inverse trans-formation method and the complex function force of launch dynamics is written by using the function li-brary of ADAMS software. The virtual prototype model of the type of equipment is built in terms of the moving, firing, and road surface based on multi-body system dynamics and vehicle terramechanics, with the aid of the 3D drawing software CREO and multi-body dynamics analysis software ADAMS and finite element software ABAQUS. With the model’ s correctness verified through experiments, the simulation calculation and research are to be conducted of self-propelled gun dynamic response characteristics of two crucial positions. The results provide a reference for the study of the fire control system of this type of equipment, projectiles scattered law firing on the move and the sighting position interference.
