摘要：

For lack of research on degradation test (DT) for molecular sieve oxygen concentrator (MSOC) and clear account of the factors causing degradation failure of molecular sieve bed (MSB), a DT design method of MSOC based on orthogonal test was proposed. Based on the working principle of MSOC, the main factors causing degradation failure of MSB were determined, and a DT system of the MSOC was built. The optimal test height for the DT was 9 km, as was determined and verified by several controlled tests. A DT scheme of MSOC was designed based on the orthogonal test idea. The influence of various factors could be obtained through 9 typical tests, which reduced the test times and costs, and improved the efficiency of coupling tests. The test design can simulate the real working environment, and can effectively reduce the impact of test factors on the initial value of the test results. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
