Design And Implementation Of Comprehensive Test Equipment For A Certain Type Of Aircraft

Comprehensive test equipment is used to test the aircraft's function and performance in its development process.It can give the corresponding test stimulus and synchronous data acquisition in the process of testing.Test results are given after the data processing and storage.The test equipment should have good generalization ability and self ability,which can be extended for test of the follow-up model.In this thesis,the comprehensive test equipment is developed to meet the requirements of the aircraft.In this thesis,the hardware and software requirements of the measured object are analyzed.A test equipment base of hardware platform based on PXI bus technology and the PXI instrument resource module mature is built according to the principle of modularization,generalization and serialization.Interface adapter,dynamic excitation device,target simulator and self checking device are designed.The test equipment has met the requirements of the current project test and can be used for similar projects or subsequent upgrade projects.According to the characteristics of the tested object and test requirements,the method of uploading and injection are used to achieve the test.The test software is divided into the upper computer test software and the next bit machine testing software.It is mainly composed of the object test,the equipment test,data processing and playback,report generation and equipment resource call and other functional modules.The comprehensive test equipment has been used in the actual test of the aircraft.It is stable and reliable,which has friendly interface and can be easy to operate.It also has a strong expansibility.
