Abstract

The invention discloses a method for determining the correlation degree of the synergy effect of the space environment. The method includes determining the high and low temperature alternating environment according to the orbital environment; selecting composite materials and subjecting them to several space environment states in groups; completing the environment according to the test plan. Effect test; according to the effect equivalent principle, determine the atomic oxygen test dose and test machine time; formulate thermal cycle test parameters; complete the two-factor environmental matrix test, and test the performance parameters of the test samples after the test; test the test data in the matrix table Carry out cross-comparison, respectively and the simple sum ratio of the single factor test results, namely the additivity coefficient. Through the understanding, processing, extrapolation and exploration of ground single factor and sequential action test data, the present invention can predict and predict the simultaneous action effect of on-orbit space environment factors, and effectively improve the effectiveness of space environment test research.

Description

technical field [0001] The invention belongs to the technical field of space environment and effect testing, in particular, the invention relates to a method for determining the correlation degree of synergy effects in a space environment. Background technique [0002] At present, the development of aerospace technology has led to the need to study the damage of spacecraft materials in the space environment, so that the spacecraft can achieve aerospace tasks in a safe situation, but in the space environment simulation conditions of spacecraft materials , requires a full understanding of the following correlation effects. [0003] 1) Space environment and its effects [0004] The influence and damage of the complex space environment on space structural materials are important factors that cannot be ignored, and it will directly affect the normal operation, work and service life of the spacecraft. Understanding the space environment and its effects, and mastering the influen...
