The main contents of this paper are the research and calculation of the separation action reliability of the missile and its adapter. After establishing the dynamic and kinematic equations of the adapter during its separation action, the authors analyse the random factors which have effects on the reliability of the separation action, and define the random variables according to the engineering condition. In order to calculate the reliability of the separation action, a failure criterion is defined, and the G-function is established according to the response surface method. At last, the reliability of the separation action is calculated by using the first-order second-moment method and the Monte Carlo method. The results show that the reliability analysis and calculation method can satisfy the missile engineering developing requirements.
