Abstract

Aiming at the problem of noise during the operation of the pyrotechnic separation device, this paper uses LS-DYNA software to simulate the separation process of the separation nut. Then uses the LMS Virtual.Lab software to predict and analyse the mechanical impact noise during the separation, and quantitatively decoupling the contribution rate of the mechanical noise generated by the movement of each component. The results indicate that the inner sleeve impact is the main source of mechanical noise during the separation (more than 90 %).
