[Abstract]:In this paper, a certain kind of auxiliary power plant of an airline is used as the background, and its simulation and test platform is designed and developed. The auxiliary power unit (APU) is essentially a small gas turbine engine capable of providing pressurized gas sources and shaft power for starting the main engine, driving the hydraulic pump, and providing the aircraft with a backup hydraulic source and power supply for the generator. Provide air supply to cabin air conditioning system. Because of the complex structure and high price of APU equipment, it is impossible to test the performance and parameters of the system with real equipment at any time. It is also unfavorable to the development, performance improvement and fault diagnosis of the system. Therefore, it is very important to develop and design a test platform that can replace the real equipment to complete the simulation of APU function and running characteristics. This paper designs and develops the simulation test platform of auxiliary power device. First, the function, characteristics and development status of the automatic test system are introduced, then the overall scheme of the system is determined from the function structure of the auxiliary power device and the control requirements of the test platform. Then how to build the simulation model of APU system based on MATLAB/SIMULINK, and build the modular system hardware structure based on PXI test bus, use VeriStand software to complete the development of main control software, and according to the need of system test experiment, the paper describes how to build the simulation model of APU system based on VeriStand, and builds the modular system hardware structure based on PXI test bus. The corresponding experimental configuration is completed, and the display and monitoring interface of the test platform is built by using Lab View software. In addition to providing a virtual simulation test environment, the test platform also provides a simulation interface between APU and ECU to complete the connection with real parts or emulators. Through actual operation and debugging, the correctness and reliability of the test platform are verified. At the same time, the system also provides the function of fault injection, which provides the possibility for the fault simulation and diagnosis of APU. The simulation test platform designed in this paper conforms to the aviation industry standards and specifications, and the products have been put into practical application. At present, the platform is in the trial operation stage, and the expected results have been obtained.
