Abstract

With the gradual development of industrialization, the reliability engineering requirements of products are gradually increasing. The characteristics of high reliability and small number of samples are especially important within the aerospace field. In order to improve the reliability of the aircraft hatch lock mechanism, this paper combines support vector machine and kriging methods for failure rate calculation and sensitivity analysis, and uses Monte Carlo methods for validation. The reliability optimization is carried out through the validation results, and the design of the lock mechanism is improved, which significantly reduces the failure rate of the lock mechanism and also provides design ideas for other mechanical structures.
