| Abstract: | Several typical joint structure used in the solid rocket motor was introduced briefly.The advantage of the snap ring was summarized by comparing with other joint structure.The snap ring joint structure is used more and more in the current military equipment.The deformation and sealing under high pressure,fit clearance and assemble process etc,were investigated comprehensively.Snap ring structure was analyzed by using the finite element method and the mechanical experiment.The research results proved that the snap ring joint structure is reasonable and feasible. |
