Abstract:
Accumulator is an important device used for POGO prevention of liquid rockets. In this paper, a general and accurate dynamic model of bellows accumulator was developed by theoretical derivation. A corrected method of compliance and inertia parameters considering the mechanical stiffness, moving mass and number of bellows subassembly was present. This model improves the precision of the frequency calculation of the fluid feeding system. As to the accumulator with charging duct, a distributed parameter model was introduced to research the influence of a long duct for the accumulator. The research shows that a long charging duct will make additional volume and meantime introduce low frequency vibration, which affects the accumulator performance.
