Abstract: In order to analyze the gear manufacturing process by measuring the gear meshnoise, a noise measurement system was developed. The hardware of the system was used to collect and analyze the gear noise signal, and the processed results of noise could be realtime displayed. Further more, in order to contrastively analyze the noise signal, a USB module was used to communicate with PC. FFT&ZFFT analysis method was applied in the interface, the analysis results could also be realtime displayed and preserved. Finally, test results show that this system can collect and analyze the gear meshnoise accurately, and analyze the characteristic frequency of gear noise efficiently, so it can be used to analyze the gear manufacturing process.
Key words: meshnoise; USB communication; ZFFT analysis; characteristic frequency
