摘　　要：在航天器热平衡试验中,散热面区域的低热流密度要求往往难以实现。在以往的试验中,考虑到加热笼覆盖系数对热流密度均匀性的影响,通常选用红外灯阵作为主要的外热流模拟装置。但是红外灯阵体积和热容较大,形状适应性不强,对试验容器空间要求较高。文章利用仿真的手段研究了加热笼的覆盖系数对热流密度均匀性的影响,探讨了利用红外加热笼进行低热流模拟的可行性。In thermal balance testing of spacecraft,it is difficult to achieve a low flux on radiator surfaces.Infrared lamp arrays have long been adopted as primary simulation equipment of thermal flux,considering the effect of cover coefficient of infrared heating cage on flux uniformity.But large volume and thermal capacity of infrared lamp arrays reduces its flexibility and puts more severe requirements on testing vessel,making its installation and suspending work more complex than when using infrared heating cage...
