摘要
高速飞行器流固界面热力载荷的快速高效转换是结构热气弹分析的重要前提。本文分别基于最小势能原理建立了流固界面热力载荷的转换方法,并编制了相应的转换软件,可实现不同单元类型、不同载荷类别、不同软件之间的双向热力载荷转换。测试算例表明,无论是定量分析还是定性分析,本文方法都能实现流固界面热力载荷的高精度快速转换。
The rapid and efficient conversion of thermal loads on high speed aircraft fluid-solid interface is an important prerequisite for structural thermal aero-elastic analysis.Based on the principle of minimum potential energy,this paper establishes the conversion method of fluid-solid interface thermal load,and compiles the corresponding conversion software,which can realize the bidirectional thermal load conversion between different unit types,different load categories and different software.The test examples show that whether it is quantitative analysis or qualitative analysis,this method can achieve high-precision and fast conversion of fluid-solid interface thermal load.
