Abstract:

The sealing process of a flashboard-type normally open pyro-valve is simulated with LS-DYNA software in order to select a suitable structure for it. Both of the relationship between stress curve and time as well as the moving process figure during the matching period of seal parts are gained from different structures. According to the simulation, the seal configuration of the flashboard-type normally open pyro-valve is selected. It is proved to be successful in prototype manufacture.
