As a test the vibration of the satellite components and the characteristics ofthe driven equipment, mechanical drive transmission device mainly used fortesting the solar panels drive mechanism vibration properties and the mechanicalparameters of the equipment.Under normal circumstances, the vibration ofmechanical parts is harmful. Mechanical vibrations tend to destroy normal workand the original performance, mechanical parts will also form the dynamic load inthe movement, accelerating mechanical parts failure, shorten service life, and evenlead to irreversible damage.In order to improve the reliability of mechanicalcomponents, it is necessary for mechanical parts for mechanical structure vibrationanalysis and testing.And these data needs to be by a specific system for dataacquisition and data analysis. This topic mainly describes drive transmissiondevice in the design and implementation of data acquisition and analysis method.This paper first discusses the drive in the transmission of vibration principle,and introduced the mechanical vibration test of the structure and the selection ofequipment.In the whole vibration test experiment, the data collection of the mostimportant part also made detailed instructions, and then points module introducesthe hardware structure of the system.Data acquisition is completed to analyze thedata, thus raises the algorithm of data processing and analysis.In the process of data processing and analysis, in view of the driving gear ofthe demand of data acquisition and analysis system,on software systems used inthe circulation of the cache method ensures the accuracy of the data collection,using the vector kalman filter for circular raster data acquisition of real-timeprocessing.At the time of data analysis, the system adopts the means of timedomain and frequency domain analysis, time-domain analysis using average valueanalysis, fengfeng analysis, variance analysis, etc.Because the traditional fastFourier transform have no time to locality, so this system adopts the add windowFourier transform part of the signal in the frequency domain analysis. Throughthese algorithms make system with higher stability and accuracy.As interactive software, drive gearing the PC software adopts the modulardesign of control system of C/S architecture.And the design fully consider thefriendly man-machine interface, meet the experimental requirements of users.Thewhole software design ensures the accuracy of the data acquisition, has goodscalability, data processing speed, suitable for use in industrial control. |
