Abstract
In order to prevent the harms caused by too large ship shafting vibrations when the performances of vibration dampers declined during the ship moving，an algorithm of analysis and extraction of the phase angles of ship shafting vibration dampers in frequency domain was proposed herein,a twist vibration meter was used to constantly measure and compute the inner and outer angular velocities of vibration dampers，the phase angles and damping coefficients of the vibration damper were obtained and error reasons were analyzed，large error data were excluded ，then the fitted curves were compared with standard curves to estimate the performances of vibration dampers.The prototype test results show that the algorithm may accurately calculate the phase angles of the vibration dampers，and the fitted curves are of high accuracy，which satisfy the design requirements on ship shafting performances of vibration dampers.
