摘要
为研究内置式重力空射火箭运动出舱的安全性,应用多体动力学软件(ADAMS)构建了重力空射载机-箭-伞系统的动力学仿真模型,利用动态链接子程序实现了气动力的加载,分析了稳定伞阻力特性、滚轮摩擦系数、载机飞行速度和载机飞行俯仰角对火箭出舱安全性的影响,根据仿真计算结果得出了影响因素对火箭运动出舱整个过程安全性的影响规律。
In order to research the security of rocket extra- cabin for internally gravity air- launch,the aircraft- rocket- parachute dynamic model is established based on multi- body dynamics software ADAMS;the aerodynamic forces are applied with dll subroutines. The influence factors and influence rules of the whole process safety of rocket extra- cabin are obtained by comparative analysis of the influences of launch pitch angle,wheel friction coefficients,speed of aircraft and pitch angle of the aircraft on the results.
