碩士 === 國立中央大學 === 機械工程研究所 === 97 === This thesis mainly takes deals with the vibration theory and the signal processing as the basis; develops spectral analysis software of set to belong to under the vibration test system. The control interface takes the LabVIEW software as the data acquiring, in order to acquires the signal of the hammer and accelerometer, using LabVIEW constructs the signal processing program of transformation and the operation, providing major function for natural frequency analysis and seeking for the damping ratio, can also demonstrate various channel’s the time domain and frequency domain signals. Matching the DAQ card (PCI-4461) , it makes software to have the extremely data acquire ability, and materials may penetrate the analysis program which in LabVIEW software constructs to make the immediately analysis, enable the chart which presents for the user to use . And the characteristic of LabVIEW software is lying in procedure go on as a means of way that material flow and data acquire, material analysis operation can go on in step under the same environment, there is one thing to do for users is offering the correct experiment materials signal, LabVIEW software will make operation out by oneself user''s required data and figure which are for users to solve the vibration problem.
