摘要:
在制导炸弹半实物仿真试验中经常发现,同一发制导炸弹多次仿真的俯仰角差别较大,同一批次制导炸弹投弹试验的遥测俯仰角与仿真俯仰角差别也较大,但是俯仰角的收敛趋势均一致,实测脱靶量与仿真脱靶量都合格,且具有一致性。为了分析出现上述现象的原因,基于协方差分析描述函数法(CADFT),建立了制导炸弹半实物仿真系统的误差传播理论,计算了仿真姿态角和姿态角速度的误差。分析了仿真姿态角和姿态角速度的误差对仿真结果的影响。结果表明,在仿真系统各种误差中,气动力和气动力矩误差是主要误差,是引起仿真俯仰角差别的重要原因; 姿态角的动态验模方法不适用于制导炸弹仿真模型,而脱靶量的静态验模方法适用于制导炸弹仿真模型。
Abstract:
In the process of guided bomb hardware-in-loop simulation test,the difference among pitch angle simulation results of the same bomb is larger,and the difference between pitch angle telemetering results and simulation results is also larger by one batch guided bomb,but the convergence of pitch angles is consistent,and the tested miss quantity and the simulated miss quantity are also consistent. Aiming at this problem,the error propagation theory of guided bomb hardware-in-loop simulation system was established based on the covariance analysis describing function technique(CADFT). The simulated attitude angle errors were calculated as well as the errors of attitude angle velocity. The influence caused by simulated attitude angle errors and attitude-velocity errors on simulation results was analyzed. The result shows that the aerodynamic force error and aerodynamic torque error are the main reasons causing the difference among pitch angle simulation results. The dynamic verification method by attitude angle isn’t suit for guided bomb simulation model,but the static verification method by miss quantity is suitable.
