Research on Optimization Simulation for Elevating System Control Target Automatic Aiming of a Rocket Launcher

某火箭炮高低控制目标自动瞄准主要依靠高低随动系统完成,对自动瞄准进行优化可以提高调炮的速度与精度,但难点在于受工况条件多变的影响,同时考虑到试验成本等因素,无法对现有实际装备元器件进行调整优化,故采用虚拟样机仿真计算的方法实现自动瞄准优化,利用ADAMS和EASY5软件分别建立了高低随动装置多体动力学模型、液压系统模型以及伺服控制模型,以软件接口方式实现机电液联合仿真,通过与实验对比进行模型准确度校核,并调整液压系统和控制系统的相关参数,优化仿真自动瞄准调炮过程。仿真结果表明:调整控制和液压系统参数,可以实现提高自动瞄准调炮的速度与精度的目的。对高低随动系统建立的虚拟样机模型是准确可信的,对提高自动瞄准调炮的速度精度是可行的,对液压和控制系统的优化是有效的。

The automatic aiming of elevating system control target of a rocket launcher mainly depends on the ele- vating system, and automatic aiming optimization can improve the accuracy and speed of adjustment of guns. Howev- er, the difficulty is that it is affected by the condition variable. Meanwhile, in view of the test costs and other factors, the existing equipment components cannot be optimized. The virtual prototype method was used to realize the automatic target optimization. A muhi-body dynamics model, a hydraulic system model and a servo control model of the elevating servo system were established by using ADAMS and EASY5 software respectively, and the electro-mechanical -hydraulic co-simulation was realized by software interface and the model was used to check the accuracy of the model and adjust the related parameters of the hydraulic system and control system, automatic aiming adjustment gun process simulation and optimization. The simulation results show that the aim of improving the speed and accuracy of automatic aiming gun can be achieved by adjusting the parameters of the control system and hydraulic system. The virtual prototype model of the elevating servo system is accurate and reliable, and it is feasible to improve the accuracy of the automatic aiming gun.
