Abstract

The invention relates to a target heat radiation analyzing method in a space environment simulating device. A space three-dimensional simulation scene is firstly established adopting a simulation method, and a heat effect model and a test target is included in the scene; then a heat equation of the test target is established according to determined heat effect model; then a working condition parameter is input, and solution is conducted on the heat equation; and a temperature field and an infrared radiation field of the whole scene are finally generated according to the solved equation. According to the target heat radiation analyzing method in the space environment simulating device, a large spherical vessel, a heat sink, a solar simulator, a background radiation simulator, a test track and device, a rotary table and an observation window simulation scene are adopted, radiation heat transfer analyzing is conducted coupling three-dimensional unsteady state, and thus radiation field with waveband of 30-50 mum can be accurately simulated.

Description

technical field [0001] The invention relates to a space target simulation simulation measurement technology, in particular to a space target infrared radiation and heat transfer analysis method. Background technique [0002] In the infrared radiation simulation test of space targets, the infrared radiation of the target itself is often inaccurate due to the interference of the surrounding environment and the scattering, radiation characteristics and small-angle characteristics of special coating materials. Therefore, it is very important to build a simulation model of the optical characteristics of a space target to analyze the infrared radiation of the target to assist in the measurement of the temperature, radiation, and scattering characteristic parameters of the target in a vacuum cold environment. [0003] Infrared radiation is a means to investigate the optical properties of the target. A space target infrared radiation thermal analysis model is established, and these ...
