轴承腔热分析通用软件的开发与应用

摘要

A new general software of bearing chamber thermal analysis for turbine engine is developed. Thermal network method is used to establish heat balance equations,on which thermal analysis is based. A visible graphic interface is developed with DELPHI and is used to build models, input and output data, while a main program developed by FORTRAN is used to calculate. All these contribute to software's generalization and suitability. Compared with experiment results,the software has a good accuracy.%为满足航空发动机设计需求,开发了一种全新的航空发动机轴承腔热分析通用软件.软件基于可视化图形建模技术与热网络算法,通过构建轴承腔热网络模型图来完成热分析计算,具有良好的通用性与适用性.软件前台是采用DELPHI编写的图形界面,可以完成图形建模、参数输入与输出；后台是基于热网络法建立的各节点热流平衡方程组,通过FORTRAN编写的主程序进行热分析计算.软件能够获得轴承腔细致的温度场分布以及热状态变化规律,通过与试验数据对比,软件具有良好的计算精度.
