导弹空中挂飞分离试验仿真计算

导弹设计时必须考虑其投放过程中与载机分离时的安全性问题.利用计算机数字仿真技术进行导弹分离安全性分析是一种非常经济、有效的方法.在某型导弹挂飞试验中,我们以Euler方程和刚体六自由度运动方程为理论基础,完成了对该某型导弹在试验选定的各种速度、迎角下的投放分离轨迹进行了计算仿真,取得了非常满意结果,载机实际试飞验证表明,试验数据与理论计算结果十分吻合.该结果也证明了Euler方程和刚体六自由度运动方程在工程应用上是非常有效的,特别是对于具有一定长细比结构体的空中运动轨迹分析计算是非常适用的.

Simulation of the Aerial Embarkation Flight and Detachment Tests of a Certain Type of Missiles

During the design of a new missile,safety in the detachment between the missile and its carrier plane in the launce test must be considered.At present,the utilization of computer digital simulation in missile detachment safety tests is very economical and effective.In a certain type of missile embarkation flight tests,the computation and simulation of launch and detachment tract in a variety of velocities and attack angles are accomplished according to Euler equations and six degrees of freedom of rigid body.The test data tallies with theoretical computation accurately,which proves the simulation satisfactory.At the same time,the effectiveness of Euler equations and the kinetic equations of six degrees of freedom of rigid body is verified in engineering simulations,especially in aerial tract analysis and computation of structures with some aspect ratios.
