Abstract: Due to the long-term complex working conditions of the ship seal, its sealing performance will be greatly reduced. In view of this problem, the optimization design of the ship's stern shaft seal structure was studied.First of all, the structural principle of the ship's stern shaft seal was analyzed, and the friction power consumption, the maximum deformation of the sealing end face and the leakage amount were defined as the sealing performance parameters. Secondly, the finite element method was used to establish the performance analysis model of the ship's stern shaft seal, and the research route was determined. The change law of the sealing performance of the ship stern shaft seal under different structural parameters was presented. Finally, the response surface method was used to optimize the typical structural parameters of the dynamic and static rings of the seal, and the objective equation of each sealing performance parameter was established. A test bench for ship stern shaft seal was built, and the simulation results were verified. The research results show that the optimized structure reduces the end face deformation by 9.8% and the leakage by 5.7% compared with the initial design structure, which can effectively improve the sealing performance of the seal, and provide ideas for the design and optimization of the ship stern shaft seal.
Key words: mechanical seal structure; overall sealing performance parameters; friction power consumption; maximum deformation of sealing end face; leakage amount; seal static ring optimization; structural parameter optimization
