Description

Technical Field

[0001] This invention relates to the field of final assembly testing, and more specifically to a support device for a final assembly testing dark box. Background Technology

[0002] Currently, the test chamber support devices used in the final assembly and testing of aerospace products suffer from structural and height mismatches with the tested products, as well as connectivity issues with electrical signals, networks, and test signals. This makes it impossible to complete tests such as electromagnetic compatibility, performance, and flight status. Ground testing faces multiple critical defects, directly impacting test effectiveness and product reliability. Positional misalignment may lead to distorted test data, preventing accurate performance verification and allowing products with minor deviations to enter the launch phase, increasing the risk of on-orbit failure. Current test support devices also cannot stably secure the product and may damage the tested component due to structural failure, leading to test interruptions or product scrapping. Temporary support structures are not only time-consuming and labor-intensive but also struggle to ensure consistency in each support, significantly extending the testing cycle and increasing the cost of repeated testing, failing to meet the demands of efficient aerospace product development. Temporary supports may also introduce electromagnetic interference or release contaminants, interfering with signal acquisition, contaminating the tested product, and rendering test results invalid, making it impossible to accurately determine whether the product meets usage standards. Therefore, there is an urgent need for an adjustable and stable test chamber support device. Summary of the Invention
