Sealing Performance of Pressure-Adaptive Seal
文献摘要:
A pressure-adaptive seal is developed to meet the demands of quick assembling and disassembling for an individual protection equipment in aerospace.The analysis model,which reflects the main characteristics of the seal structure,is built based on the finite element method and the Roth's theory of rubber seal,and verified by the prototype test.The influences of precompression ratio,hardness of the sealing ring rubber,and friction coefficient on the sealing performance are investigated by variable parameter method.Results show that the model can describe the essential characteristics of the pressure-adaptive seal structure,which has good follow-up to the cavity pressure to achieve the purpose of pressure self-adaptive.The leakage rate correlates negatively with the precompression ratio of the sealing ring and the hardness of the sealing ring material,while is positively related to the friction coefficient between the sealing ring and the sealing edge.The maximum contact stress on sealing surface has negative correlation with the precompression ratio of the sealing ring,and positive correlation with the hardness of the seal ring material.The damage risk of the sealing ring increases with the increases of the precompression ratio of sealing ring,hardness of sealing ring material,and friction coefficient.
