Abstract: To improve the efficiency and intelligent level of spacecraft mechanical environmental testing, this paper systematically investigates a technical framework for its digital and intelligent transformation. Key technical stages, such as test plan design, control parameter optimization, and test data analysis and mining, were identified, leading to the establishment of a comprehensive development framework. The study also analyzes existing challenges and proposes targeted solutions. For technologies that have been preliminarily applied, specific implementation schemes and application outcomes are provided. This work provides a systematic approach and practical solutions for advancing the intelligent development of spacecraft mechanical environmental testing technologies.
