Abstract

The invention discloses a test intensity evaluation method based on multi-source environment fusion, relates to the technical field of environment fusion, and is used for solving the problem that the refined regulation and control capability of a test process is limited due to the fact that dynamic quantitative evaluation and grading judgment of test intensity cannot be realized. The method comprises the following steps: collecting salt mist sedimentation data, in-cabin wind speed data and a surface wet film signal, constructing a multi-source environmental parameter collaborative change characteristic, extracting a salt film conduction trend in combination with surface conductivity, forming an environmental collaborative index, introducing historical salt mist duration and pre-tightening force data, constructing a corrosion sensitive state, and performing state correction on environmental action intensity. Salt mist strength characteristics are comprehensively calculated through the strength modulation coefficient and the environment coordination index, salt mist strength grading is achieved in combination with grading judgment intervals in the corrosion standard library, fusion evaluation of environment loading, the material state and historical corrosion accumulation is achieved, and grading judgment and dynamic regulation and control of the test process are supported.
