开发了一种通用的航空发动机附件机匣热分析计算软件。软件综合热网络法和有限元法的优势,用Fortran语言开发了基于热网络法的附件机匣内部元件热分析模块,用APDL语言开发了基于有限元软件ANSYS的壳体热分析模块,两个模块之间存在数据交换和迭代联算。软件具有通用性,可以满足各种不同结构的附件机匣热分析计算。通过对某航空发动机附件机匣进行热分析计算,获得了附件机匣的温度场分布、生热量以及滑油出口温度,说明了软件应用于附件机匣热分析计算的可行性。 Developed a common aeroengine attachment box heat analysis and calculation software. Based on the advantages of thermal network method and finite element method, a thermal analysis module based on thermal network method is developed using Fortran language. The shell thermal analysis module based on finite element software ANSYS is developed with APDL language. Two There is data exchange between modules and iterative calculation. Software has versatility to meet a variety of different configurations of the thermal analysis of the receiver casing calculation. Through the thermal analysis and calculation of the casing of an aero-engine attachment, the temperature distribution, the heat generation and the oil exit temperature of the casing of the attachment were obtained, which illustrated the feasibility of the software in the thermal analysis and calculation of the casing of the attachment.
