| ObjectiveTo solve the problem that it is unable to satisfy both the high and low temperature condition needs for heat flux simulation solely depending on design of infrared heating cage in vacuum thermal tests.MethodsA movement driving system was designed and successfully used in project tests. The capability of heat flux simulation was vacuum thermal tests；infrared heating cage；heat flux simulation；movement driving system regulated by adjusting the relative position of infrared heating cage under different conditions during the tests.Results The application results indicated that this system could overcome the impact of high vacuum and ultralow temperature environment，satisfy the mechanical and electrical interface requirements for space environment simulator and drive the infrared heating cage to move steadily and reliably，and acquired an obvious improved index for heat flux simulation.ConclusionIn vacuum thermal tests，by adjusting the relative position using movement driving system can make the infrared heating cage to satisfy the needs much better for different conditions and improve the synthesis ability for heat flux simulation. |
