Description

Technical Field

[0001] This utility model relates to the field of inertial navigation environment screening and testing technology, and in particular to a modular tooling for inertial navigation environment screening and testing. Background Technology

[0002] As a core navigation component of various weapons, equipment, and aerospace vehicles, the environmental reliability of inertial navigation systems directly determines the navigation accuracy and mission performance of the entire system under complex operating conditions. To ensure that it meets stringent environmental adaptability requirements throughout its entire life cycle, comprehensive environmental screening tests must be carried out at multiple stages to expose potential defects early and eliminate products that fail early.

[0003] However, current inertial navigation temperature environment screening tests still face many practical constraints: on the one hand, the testing process needs to balance efficiency and feasibility due to limitations in test site space, equipment resources, and personnel allocation; on the other hand, conventional environmental testing equipment (such as high and low temperature test chambers) often adopt large-volume chamber designs in pursuit of batch testing efficiency, resulting in long product handling paths and limited operating space. Especially when the chamber depth is large, operators need to reach deep into the chamber for disassembly and assembly, which not only results in high labor intensity and low work efficiency, but also poses a risk of product damage from bumps and knocks, making it difficult to meet the high-efficiency testing requirements of the mass production stage.
