Abstract

The invention discloses a comprehensive environment experiment study system of an astronavigation optical cable connector. The system comprises a vacuum system, a low-temperature system, a temperaturecontrol system, a tool system and a testing system, a vacuum container of the vacuum system forms an airtight space, a bearing platform for a tested product is mounted on the lower side of, the low-temperature system provides cold-black environment simulating spatial low temperature and free of reflection state for the product, a measuring signal of a temperature measuring sensor is changed underthe temperature control system by changing surface temperature of a connector, a heating device fixing tool in the tool system is placed on a vacuum container mounting platform and used for fixing aheating device to a specified position around the tested product, and an optical fiber connector truly simulates mounting mode and heat transfer path in an in-orbit working condition. The comprehensive environment experiment study system is simple in structure, capable of realizing effective control, convenient for mounting and debugging and easy for design and implementation of various stress experiment matrixes.

Description

technical field [0001] The invention belongs to the technical field of comprehensive environmental testing of aerospace optical communication devices, and specifically relates to a device for conducting research on ground simulation comprehensive environmental experiments for aerospace penetrating connectors. Background technique [0002] With the significant increase in the amount of data transmitted by spacecraft in orbit, the high-speed, accurate and reliable transmission of data on the spacecraft has become an important symbol for improving the performance indicators of spacecraft communication systems. The spacecraft transmission bus gradually develops from the traditional cable network to the optical cable network. With the application of optical cables from inside to outside the cabin, the application environment of optical cables becomes very harsh, such as the alternating high and low temperature environment with a temperature of -150°C to 150°C. These environmental...
