Abstract


With the increasing development of the shipping industry in China and people are more and more in-depth understanding of shafting vibration hazards , the increasing demands of the the ship shafting vibration signal measurement and analysis technology . Firstly, starting with the analysis of the formation of the ship shafting vibration and hazards described research portable ship shafting vibration measurement and analysis instrumentation purpose and meaning , and then discuss the status quo and development trend of the of shafting vibration measurement technology development . Then the principle of shafting vibration measurement technology research, and completed the first test the design of a portable ship shaft vibration measurement and analysis instruments . The instrument uses a laser sensor to achieve accurate real - time signal acquisition torsional vibration ; CPLD (Complex Programmable Logic Device) , complex programmable logic device system signal acquisition and processing functions ; microcontroller control system ; to use FLASH achieve data files capacity storage ; LCD (Liquid Crystal display ) a liquid crystal display to achieve the vibration waveform and the real time display of the data ; universal serial bus interface , a USB ( Universal serial Bus ) , a portable unit with a PC ( Personal Computer ) of high speed data transmission. Portable signal simple signal processing , waveform display , FFT (Fast Fourier Transform) transform amplitude spectrum display ; the PC machines signal processing systems analysis functions , including time-domain analysis, spectral analysis, coherence analysis and time-frequency analysis in the short-time Fourier transform and wavelet analysis . In this paper, the system 's hardware design , software design , as well as the PC signal processing system design . And system verification of functional simulation and data processing , to verify that the system is running stable and reliable , the features working , accurate data analysis , operation speed, high precision, achieved the desired design purposes .
