| 摘 要： | 可信性与实时性是"人在回路"仿真系统研究的核心内容.在仿真过程中,通过对坦克火力系统物理模型分析,兼顾仿真精度与实时性要求,采用与实际武器装备一致的解算方法,拟合出方位角、瞄准角、最大弹道高与测距距离的函数关系,并据此构造出装甲车辆的外弹道曲线.通过对计算机机器时间物理模型的分析,采用读取CPU内部64位时间寄存器EDX:EAX方式,实现了仿真算法的纳秒级实时运算.通过提高可信性与实时性,增强了"虚拟战车"的沉浸感,为装甲武器装备的采办提供了必要的支持. |

| Abstract: | Creditability and real-time capability is the bottleneck problems for "man-in-the-loop" simulator.Working process of tank firepower system is analyzed in advance.By adopting the similar computing method with actual weapon,azimuth and pitch angle and height of bullet trail are computed,which leads to the construction of outer bullet trail.Furthermore with the compare of several machine time models of simulation computer,Intel CPU 64-bit register of EDX:EAX is selected to realize real-time calculation with ns time resolution.The increasing creditability and real-time capability improves immersion performance of the virtual-combat-vehicle,thus enhances the supporting capability of the acquisition process for armored vehicle. |
| Keywords: | armored vehicle firepower ability creditability real-time capability modeling and simulation |
