摘　　要：针对传统诸元解算方法耗时长、精度较差的问题,提出了一种基于PSO优化的激光末制导炮弹诸元解算方法。首先,根据作用在弹丸上的气动力和作用力,建立弹丸的六自由度模型,分析了气象条件对弹丸参数的影响;应用龙格-库塔法进行弹道解算,并给出气动参数辨识方法,对弹道进行校验;分析表尺、程装等参数对射程的影响;将参数作为待优化的变量,应用PSO优化得到最优解,作为射表相应的诸元取值。最后,对所提出的方法进行仿真及实际飞行实验验证,研究结果表明,所提出的方法具有较高的精度,实际飞行试验均命中靶标。In order to the problem of long time-consuming and poor accuracy of traditional firing data methods,a calculation method of laser terminal guidance projectile firing data based on PSO is proposed.The aerodynamic force and force acting on the projectile are analyzed.The 6 degrees of freedom trajectory model is established,and analyze the influence of weather on projectile parameters.Apply Runge-Kutta method for trajectory calculation,and provide aerodynamic parameter identification method,which checks the trajectory.Analyze the impact on the range when the parameters such as rearsight change are changed.using parameters as variables,the optimal solution is obtained by PSO optimization and as the corresponding data value of the firing data.The effectiveness of the training is tested,verified by mathematical simulation and target practice.The results show that the correctness of the proposed method is verified,and with the firing data obtained by PSO method,projectiles impact the targets precisely in the flight tests.This paper provides a reference for engineering application for the future.
