舰载导弹发射动力学及其校准误差数值建模

Launching dynamics and calibration error modeling of shipborne missile

武器系统是舰船作战能力的保障,由于导弹在发生过程中与船体的运动相互耦合,是一个典型的多体动力学问题。为了提高舰载导弹的发射精度,降低舰船导弹发射的校准误差,本研究建立了舰船及导弹系统的运动坐标系,通过数学模型分析了舰载导弹发射的误差原因,并基于卡尔曼滤波器进行了舰载导弹发射过程的校准控制。SkyFly仿真平台的仿真结果表明,本研究有利于降低舰载导弹发射的误差,提高精度。

The weapon system of military warships is the guarantee of warship’s combat capability.Because warship missile is coupled with ship’s motion in the course of its occurrence,it is a typical multi-body dynamic problem.In order to improve the launching accuracy of shipborne missile and reduce the calibration error of shipborne missile launching,the motion coordinate system of ship and missile system is established in this study.The error causes of shipborne missile launching are analyzed by mathematical model,and the calibration control of shipborne missile launching process is carried out based on Kalman filter.The simulation results of SkyFly simulation platform show that the research is helpful to reduce the launch error of Shipborne missiles and improve the accuracy.
