Abstract


Vibration test and analysis techniques as a means to solve the vibration problems in engineering , has already been exploited . In the past twenty years , with the development of technology and production , vibration testing and analysis , whether in theory or in the technology and application occurred a remarkable profound changes . In the 1970s , generally promote the use of micro- computer , especially the introduction of the FFT algorithm , making the vibration test analysis technology into the new era . The system is under the Windows interface vibration, noise and signal processing system, the support of the specific analog input hardware (data acquisition system) , it can complete the data acquisition of the signal and the power spectrum of the vibration, noise , cepstrum , spectral array , and a transfer function analysis and other functions. , Data can be converted into the corresponding graphics with ZOOM function . It can be widely used in the laboratory to do the testing and analysis of vibration , noise , the production site and teaching , can replace the work of a dedicated signal processor . The system software uses advanced the C Builder languages ??prepared run under WINDOWS system . Software interface designed to meet the needs of most users , and strive to popular intuitive , menu-driven accomplish various functions .
