摘要

摘要:
针对某型航空发动机防喘系统结构复杂、故障排查困难的问题，对其利用AMESim软件进行数字化建模与仿真，重点对影响系统特性的核心部件——换算转速计算模块的建模与仿真进行深入研究；利用AMESet对钼质杆温度传感器的特殊结构建立了仿真模型，并且为方便工程上使用结合实践经验基于MATLAB APP Designer设计了应用程序。仿真结果表明：建立的模型与试验数据相比误差控制在了5%以内，能够初步完成对故障因素的验证工作，具有较高的精度与可靠性，同时APP（application）的设计也极大地提高了系统仿真和分析的效率。

Abstract:
In response to the complex structure and difficulty in troubleshooting of a certain type of aircraft engine anti-surge system, digital modeling and simulation was conducted using AMESim software, with a focus on in-depth research on the modeling and simulation of the core component affecting the system characteristics——the conversion speed calculation module. A simulation model was established for the special structure of the molybdenum rod temperature sensor using AMESet, and an application program was designed by MATLAB APP Designer to facilitate engineering use in combination with practical experience. The simulation results showed that the established model has an error control of less than 5% compared with the experimental data, and can preliminarily complete the verification of fault factors with high accuracy and reliability. At the same time, the design of the APP (application) greatly improved the efficiency of system simulation and analysis.
