Analysis And Research Of Damper Performance Test System

With the rapid development of aviation industry and its property, more and more various types of large aircraft have been created and put into use. The different performances of the aircraft will be completely displayed only if the aircrafts' security is good. The safety of the aircraft is the main symbol of judging the aircrafts' performance.To make the aircraft be more and more safe, the damper has been used in the aircraft's operation lever to improve its controllability, balance and flexibility, which improve the stationarity of aircraft effectively. The developed aircraft can show its good performance.The operation process of aircraft joystick is affected directly by the size of the performanceparameters, so measuring the performance parameter of damper has a very important significance to improve the controllability of joystick and enhance the aircraft's security. The performance detection of the existing aircraft operating rod system is mainly based on manual and semi automatic test method. The test method is simple and has no protective measures. The test results have great influence on the test results, and the testing method and the related parameters have no detection and test method. In this paper, the design pattern of distributed measurement system is put forward, which is of great importance in academic and engineering application.Based on the analysis of system functions and requirements, testing principle of performance parameters and technical parameters of damper, the overall design of this system is performed. The system is designed to be a distributed control and testing system based on IPC,PCI standard board and intelligent instrument.Secondly, the composition and function of the design measurement and control system, the design and analysis of the servo motor speed control system and the mechanical and electrical transmission system are completed. Then, based on the analysis of the whole testing system, the hardware design and software design of the control system are completed, To realize monitoring the state of the whole system,damper's speed and torque and the damper parameter display, analysis and storage, the program is designed in the Lab VIEW development platform. Finally, on the foundation of building the system, it is debugged to ensure its reliability and functional integrity by testing damper's performance parameter.The test results show that the performance test rig has the characteristics of easy control, stable performance, high reliability, high accuracy of test data and friendly interface.
