Abstract

Abstract

To improve the analysis and design method of spring metal C-ring sealing characteristics, by establishing a fine analysis model, the compression and rebound characteristic curve is accurately simulated, and the effectiveness and correctness of the numerical method are verified by the test data; In addition, the sensitivity of structural parameters is systematically analyzed by test design method, and the interaction law of design parameters on sealing characteristics is deeply studied; the optimization model is established based on Multi-Island Genetic Algorithm (MIGA), and the optimization design of key parameters is studied. The results show that the simulation results of compression and rebound characteristic curve are in good agreement with the test data, and the numerical method has very good stability; The diameter of spring wire, the thickness of sealing layer and cladding layer have an important influence on the contact pressure characteristics of sealing surface, but the diameter of spring wire should not be too large or too small; Using the optimization model and method established in this paper, the optimal combination of key parameters can be obtained quickly and the sealing performance can be improved effectively.
