With the use of ARM and DSP as the platform, a set of comprehensive on-line vibration monitoring system for marine power shaft system was developed for assuring its operation safety. The electric strain measurement, wireless telemetry and digital signal processing techniques were applied. The real-time monitoring of the operation status of the shaft system can be realized with this system. Some important parameters can be obtained on time so that the operation safety of the shaft system can be guaranteed. The monitoring system was verified by the testing on a diesel engine testing bench. Results of measurement showed that the shaft vibration monitoring system could achieve higher accuracy in monitoring.

Solving the finite element equation for vibration analysis, the force and displacement responses of a fluid-filled pipeline are obtained. Using the solution, the power flow and energy distribution in the pipeline are gained. Then, pipeline vibration can be assessed quantitatively according to the energy. Taking the energy of the average length of the pipeline as the assessment parameter, the magnitudes of vibration of the pipeline with different constraint conditions are assessed quantitatively. Comparing the results with those of the traditional displacement-based assessment method, it is concluded that the energy-based assessment method proposed in this paper is more reasonable and accurate. The energy-based assessment parameter provides an effective theoretical base for vibration control of fluid-filled pipelines.
