Abstract:

In order to achieve the ship double shaft power propulsion shafting and dynamic measurement of torsional vibration stress, the shaft power and torsional vibration stress software on measurement and analysis was developed and designed. The basic principle of shaft power, the torsional vibration stress measurement and the required equipment was described. Through ship propulsion shafting of torque and rotational speed of real-time acquisition and conversion, measuring software was able to calculate the shaft power and the torsional vibration stress and display and storage of torque, rotating speed and shaft power and the torsional vibration stress in real time. At the same time, according to the measurement turns, torsional vibration stress was analyzed in the frequency domain. The data playback can select specified measured file with playback observation.Prototype test shows that the system test precision is high. Shaft power and torsional vibration stress analysis results are showed intuitively,which satisfy the design requirements on ship's double propulsion shafting shaft power and torsional vibration stress analysis.
