Abstract

The invention discloses a method of determining space environment synergistic effect relevancy. The method comprises the steps that a high and low temperature alternating environment is determined according to an in-orbit environment; a composite material is selected and is subject to several space environment states in groups; an environment effect test is completed according to a test scheme; according to the effect equivalent principle, an atomic oxygen test dose and test machine hours are determined; thermal circulation test parameters are made; a two-factor environment matrix test is completed, and a test sample performance parameter test after the two-factor environment matrix test is performed; and crossing comparison is performed on test data in a matrix table, and a simple adductratio, namely an additive coefficient, to a single-factor test result is obtained. According to the method, through understanding, processing, extrapolation and exploration of a ground single factor and the sequential action test data, the simultaneous acting effect of in-orbit space environment factors can be estimated and prejudged, and the effectiveness of space environment test research is effectively improved.

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...
