机载导弹地面模拟发射落点仿真分析

Simulation Analysis of Ground Analog Launch Falling Point of Aircraft Missile

针对某机载导弹导轨式发射装置地面模拟发射试验设计所需导弹落点位置,以某导弹在地面发射架上发射阶段为研究目标,利用ADAMS建立了导弹发射系统动力学仿真模型,对不同温度推力和发射角工况下的发射过程进行动力学仿真,获取了导弹发射后的运动轨迹和不同发射高度时的落点位置以及拉偏条件下导弹落点位置的最大范围。结果表明,导弹的落点位置因推力、发射角和拉偏条件不同而变化,仿真结果可为导弹地面模拟发射试验防护措施设计提供参考。

Aiming at the falling point position needed from the experimentation design of rail launcher of aircraft missile analog launching based on ground,taking the launching period of missile moving from the ground launcher as the main research object,dynamics simulation model of missile launching system was established by using ADAMS.Dynamics simulation in launching under different temperature impetus and elevation states was done.Movement track and falling point from diverse launch height after missile launching were obtained,as well as the biggest extension of missile falling point under conditions of being deflected.The results show that the falling point position vary with impetus,elevation and conditions of being deflected,which will provide certain theoretical basis for the safeguard measures design of missile ground analog launching experimentation.
