In this article, a direct and key factor which affects separation parameters of satellite-rocket separation mechanism called optimization method of minimizing external moment is introduced. By changing the positions of elastic launch devices, popping process is effectively controlled. This optimization method is proved by ground test which can offset gravity, and it particularly adapts to the fixed and non-stable status elastic parameters, the distribution of all kinds of elastic devices and bias aircrafts which are hard to make the correction. The method has successfully applied to prediction and optimization for the separation of “Zhejiang University BJ Pico-satellite”. It is widely used now in practice with its easy operation.
