The invention provides an aerospace optical fiber cabin-penetrating assembly temperature gradient simulation test device and method, and aims to solve the problem that controllable cabin-penetrating assembly temperature gradient simulation test special equipment cannot be provided in the prior art. The temperature gradient simulation test device is based on a thermal vacuum test system, a simulation cabin plate is installed in a thermal vacuum container, the thermal vacuum container is divided into an in-cabin simulation space and an out-cabin simulation space, and a heating temperature control module arranged in the in-cabin simulation space is used for simulating infrared radiation during sun irradiation to heat a connecting assembly; a vacuum cold background in the space is simulated through the vacuum low-temperature module, and a test interface is arranged in the thermal vacuum container through the component performance test module arranged outside the thermal vacuum container totest the temperature gradient effect of the cabin penetrating component. Simulation of the temperature gradient effect of the cabin penetrating assembly within the wide temperature range is achieved,configuration is flexible, the implementation cost is low, the method is easy to operate and control, and the reliability of the test effect is high.

Description

technical field [0001] The invention belongs to the field of environmental reliability test of aerospace equipment, and in particular relates to a temperature gradient simulation test device and method of an aerospace optical fiber cabin penetrating component. Background technique [0002] With the continuous improvement of spacecraft information transmission and processing rate requirements, the spacecraft transmission bus gradually develops from the cable network to the optical cable network. Outside the cabin, information transmission and processing are carried out outside the cabin. As an optical cable channel, the aerospace fiber optic module has one end inside the spacecraft cabin and one end outside the cabin. It is an important information channel connecting the inside and outside of the spacecraft cabin, and it needs to withstand the influence of the environment inside and outside the cabin. [0003] Usually, the temperature environment in the spacecraft cabin is r...

However, the temperature gradient formed by the above method is uncontrollable

In addition, for simple components, when using laser, infrared lamp irradiation and other methods to simulate radiation for heating, although a temperature gradient can be formed by rapid heating of a certain section of the test piece, it cannot provide a cold background, and it is difficult to assess the low temperature situation
