摘　　要：为了提高短时间变轨、长时间滑行的上面级的仿真效率,在滑行段利用Barrar型中间轨道计算弹道,并使上面级的姿态平行于当地水平面或者与飞行速度方向保持一致;在其余飞行阶段使用六自由度动力学仿真方法,两种仿真方法根据飞行时序自动切换。通过1个仿真实例分析了以上方法的计算效率和误差,与全部飞行阶段都采用六自由度动力学仿真方法相比,上述方法可以显著节省仿真时间,误差可接受,可用于上面级的导航制导计算、轨道初步设计、空间对抗仿真等情形。In order to improve the simulation efficiency of the upper stage with an orbit composed of short time transfers and long time glidings,the Barrar-type intermediate orbit is used to calculate the path in the gliding stage and keeping the attitude of the upper stage parallel to the local horizontal plane or consistent with the direction of the flight speed.The 6-DOF dynamic simulation method is used in all the other flight stages.The two simulation methods switch automatically according to the flight timing.The calculation efficiency and error is analyzed by a simulation example.Compared with the 6-DOF dynamic simulation method used in all flight stages,the proposed method can significantly save the simulation time,and the error is acceptable,which can be applied to the calculation of navigation and guidance,preliminary orbit design,space countermeasure simulation and so on.
