Abstract

The solid rocket engine is widely used in missile. In order to expand the scope of attack, both increase specific impulse and decrease weight are become the research goal. In this paper, we take the vessel of solid rocket engine as research object, simulate the pressure of hydrostatic test, establish the finite element model of solid rocket engine vessel, solve the stress for any element in solid rocket engine vessel and find the maximum stress point by ANASYS, and then we solve reliability by the method of random analysis. According to this reliability, change the pressure which load on the inside of solid rocket engine vessel while insure reliability higher than the criticality. In this analysis, we can increase the pressure which loads the solid rocket engine vessel and we achieve the sensitivity of all parameters.
