Abstract

The invention provides a multi-satellite vacuum thermal test method and system. The method comprises the steps of carrying out the vacuum thermal test of a plurality of satellites at the same time, respectively evaluating the thermal balance conditions of all satellites and the inner surface of space environment simulation equipment, and forming a plurality of first heat transfer quantities, performing a vacuum thermal test on the single satellite, and calculating a thermal balance condition between the single satellite and the inner surface of the space environment simulation equipment to form a second heat transfer quantity, comparing each first heat transfer quantity with the second heat transfer quantity to form each external heat flow ratio, evaluating the influence of each parameteron the external heat flow ratio according to the respective external heat flow ratio when the multi-satellite simultaneous test and the single satellite test reach the same balance temperature, and adjusting each parameter to enable the respective external heat flow ratio to be close to 1, and / or evaluating the influence of each parameter on the temperature difference according to the temperaturedifference of each satellite when the multi-satellite simultaneous test and the single satellite test reach the heat balance state and have the same external heat flow, and adjusting each parameter toenable the temperature difference of each satellite to be close to 0.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a multi-star vacuum heat test method and system. Background technique [0002] At present, the satellite industry is developing in the direction of miniaturization and mass production. Efficient vacuum thermal testing is an effective way to meet the rapid and flexible production and development needs of mass satellites, reduce the development cycle, and improve the cost-effectiveness ratio. [0003] The mission of the spacecraft thermal control system is to ensure that all instruments and equipment on the planet meet their temperature index requirements under the conditions of the determined orbit, attitude and working mode. In order to verify the overall function of the spacecraft in the space environment and ensure the reliable operation of the spacecraft in orbit, it is required that all spacecraft must undergo vacuum thermal test assessment during the ground development st...
