以装备空投下降高度和时间为参量,对装备空投过程建立了三阶偏微分方程组模型,综合考虑了风速、风向、投放点及伞降过程中随机因素对投放精确度的影响,确定出最低投放高度和投放可行域,并采用蒙特卡罗方法进行了多次仿真模拟,定量分析了投放点误差对投放精度的影响,解决了实际投放中因凭经验而对投放精度不宜定量分析的问题。与采用常微分方程建立模型进行了仿真对比,结果表明:偏微分方程更有利于实现对投放过程的精确化控制,使得投放效果显著提升。 Taking the drop height and time of equipment as the parameters, the third order partial differential equations model was established for the equipment dropout process. The influence of random factors on the running accuracy of wind speed, wind direction, drop point and parachute drop was considered and the lowest The height of launch and the feasible area were put into operation. The Monte Carlo method was used to simulate several times. The impact of error of delivery point on delivery accuracy was quantitatively analyzed, and the problem that the delivery accuracy should not be quantitatively analyzed by experience was solved. Compared with the model established by ordinary differential equation, the simulation results show that the PDEs are more conducive to the precise control of the delivery process and the delivery efficiency is significantly improved.
