大型或复杂构形辐射等效热平衡试验方法

对于大型或复杂构形不能参加的不完整状态热平衡试验,提出并证明了使试验等效完整状态的必要条件,即补偿两种状态下参试部位吸收的辐射热流之差。为验证这种等效方法的充分性,利用两种热分析软件对一个构造算例的多种状态进行了数值试验,结果表明方法可行。

Thermal Radiation Equivalent Test Method of Complex or Large Structures

In the incomplete thermal balance test,which some complex or large structures can't be involved,to make the test equivalent to the real status,difference of radiation heating between the two statuses should be compensated.The proposed method was proved to be necessary and partly sufficient by two independent numerical tests on a simple satellite.
