| Abstract: |
| The work aims to conduct an accelerated corrosion test for the inner cavity of the×× aircraft slide with complex operating environment, and propose an accelerated corrosion test environment spectrum for Jiangjin area based on the corrosion effect of external environment on the inner cavity of the slide, so as to better simulate the corrosion process of the inner cavity of the slide under actual operating conditions. A accelerated corrosion test environment spectrum of the inner cavity of the slide in Jiangjin area was designed based on the reference spectrum of the accelerated corrosion test environment spectrum of the protective coating in the exposed part and the analysis of the corresponding environment. According to the parameter formulation method of reference spectrum and the specific environmental conditions in Jiangjin area, the basis for developing this environmental spectrum was designed. Parameters such as humidity and heat, UV exposure, temperature shock, low pressure and salt spray were further determined, and the accelerated corrosion test environment spectrum of the inner cavity of the ××aircraft slide was obtained. A systematic accelerated corrosion test environment spectrum of the inner cavity of the ×× aircraft slide was successfully formed. Environmental characteristics of Jiangjin area were considered comprehensively, and relevant parameters of the accelerated corrosion test environment spectrum of the exposed protective coating were referred to. By determining parameters such as humidity and heat, UV exposure, temperature shock, low pressure and salt spray, the corrosion process of the inner cavity of the slide could be more accurately simulated under actual operating conditions. This environmental spectrum can provide an important reference for aircraft manufacturers and maintenance personnel to evaluate the corrosion of the inner cavity of the slide and take appropriate protective measures. By accurately simulating the corrosion process under actual operating conditions, the prediction accuracy of aircraft structural life can be improved, so as to ensure the safe operation and maintenance of aircraft. This research has important practical significance for improving aircraft design, extending service life and reducing maintenance costs. |
