Implication

Simulation study models dynamic contact stress and leakage in aviation valve-stem friction pairs, highlighting methods to optimize pre-tightening force and sealing structures.

Key Points

  • To model the dynamic behavior and sealing performance of an aviation valve-stem friction pair under coupled multi-physics operating conditions to prevent wear, leakage, and jamming failures.
  • Integrated contact mechanics, tribology, and multi-physics coupling theory for the stem-packing sealing friction pair of a representative aviation globe valve.
  • Constructed numerical simulation models to evaluate contact stress, friction-force fluctuations, micro-clearance evolution, and leakage dynamics under coupled thermal, mechanical, fluid-flow, and vibration fields.
  • Characterized the dynamic relationships between thermal-mechanical loading, vibration environments, and micro-clearance formation governing friction fluctuations and fluid leakage.
  • Established simulation-based criteria to optimize pre-tightening force, material pairing, and structural sealing design for aerospace hydraulic control and electromagnetic actuation environments.
