The purpose of this research is to develop a complete measurement and analysis system for the hull vibration. For local vibration of ship, the measurement requests to conform with ISO 6954:1984 or ISO 6954:2000 specifications, to address this issue this study has been successfully estab- lished a feature of analysis. Thus can be processing and analyzing real time data. In addition, order analysis method is used for establishing the relationship between the vibration amplitude and the rotation speed of main engine and propeller.
This investigation had integrated the LabVIEW graphical language and modular hardware to develop an effective measurement and analysis system. The hardware adopted data acquisition NI - 9234. The Compact DAQ-9188 has been used for simultaneous measure multi-position. Through connected and internal designed, the system could be processing and integrating data immediately.
Field tests were conducted in measurement to verify the performance of the system, including effect of cable to signal quality, rotation speed confirming, applying finite element method to conform modal testing. Otherwise, the result revealed on the shipboard vibration is proven this system could be stability operating, then the system fulfills the practical application demands also widely applies in different areas of vibration measurement.
Key words: Hull vibration, Measurement system, Data acquisition,Order analysis, Modal analysis
