Abstract

The invention relates to a different-orbit-altitude background radiation dynamic simulation method and device, a computer storage medium and a background radiation simulator. The method includes the steps that according to the orbit altitude of a to-be-simulated spacecraft and the distance between a spacecraft model and the radiating surface of the background radiation simulator in a simulation system, the effective radiation radius of the radiating surface of the background radiation simulator is calculated; the background radiation simulator comprises multiple arc-shaped radiation blocks, circular areas with different radii are formed by the radiation blocks firstly, all the circular areas with the different radii are concentrically arranged to form the whole radiating surface of the background radiation simulator; and according to the calculated effective radiation radius, the temperatures of the radiation blocks with the radii not larger than the effective radiation radius in the background radiation simulator are controlled to be increased to a first target range value, and the temperatures of the radiation blocks with the radii larger than the effective radiation radius in the background radiation simulator are controlled to be reduced to a second target range value. Through control over temperature increase or reduction of the radiation blocks in the different radius positions of the background radiation simulator, radiation heat flows at different orbit altitudes can be simulated.

Description

Technical field [0001] The invention relates to a radiation simulation method, in particular to a dynamic simulation method, device, computer storage medium and background radiation simulator for background radiation at different orbit heights. Background technique [0002] In the existing space environment simulation tests, the background radiation simulator does not consider the influence of flight altitude on the radiant heat flow, that is, the distance and angle relationship between the target and the radiant block are not considered in the radiant heat flow simulation process. [0003] Therefore, how to effectively simulate the radiant heat flow of different orbital heights in the space environment simulation test system is an urgent problem to be solved. Summary of the invention [0004] The purpose of the present invention is to solve at least a part of the technical problems in the prior art. It provides a dynamic simulation method, device, computer storage medium and backgr...
