| Abstract: | The stimulant experiment for a J patrol craft was carried out by using SCADAIII data collecting implement and CADA-X signal analysis system from Belgian LMS. The Modal caculation and the ship hull vibration prediction of the craft were carried out based on the 3-D finite element model and FEM using ANSYS structural analysis software. Reliability of 3-D finite element method was verified by comparing with data obtained from stimulant experiment and calculation results from FEA.And some meaning results of the total ship vibration were obtained . |
