Applications and effects of pyrotechnic explode loading in shock environment simulation experiment of rocket separation

Characters of rocket separation shock environment and its effects on instruments on the rocket are introduced in this paper.Method of pyrotechnic explode loading in separation environment simulation,which can reappear real pyroshock environment and produce strong shock environment to meet the requirements of qualification test and other inclementer test,is also been studied.This method can not only be used to single-machine test,but also be used to stage test and shock environment simulation of tri-dimension at the same time in certain conditions.
