为了使前级分离体达到快速分离和快速增速的目的,以满足工程应用的要求,设计了一种快速分离装置.利用爆炸点火方式点燃发射药,实现前级分离体的快速分离、发射,并应用密闭爆发器原理和内弹道理论,建立爆炸点火方式下快速分离、发射的理论模型.结合四阶龙格库塔法,对上述理论进行数值计算,得到了爆炸点火分离过程各物理参数的规律,并通过静态台架实验进行验证.结果表明,分离时间达到μm级,分离速度达到200m/s,理论计算与实验结果吻合较好.

In order to make the pre-stage separate&body separate rapidly and accelerate rapidly,and meet the requirements of engineering application, a kind of fast separation device was designed. Explosion ignition method was designed to realize rapid separation of the pre-stage separated-body. Based on the outbreak of airtight device principle and interior ballistic theory,a theoretical calculation model of rapid separation by explosion ignition was established. Combined with four-order Runge-Kutta method, the law of each physical parameter of the blast ignition separation process was obtained by numerical simulation, and it was verfied by the static bench experiment. The experimental results indicate that the separation time reaches microsecond level,and the separation speed reaches 200 m/s. The experimental results are coincident with the theory results.
