| Abstract:In order to predict the vibration level of the motor in the design stage of the marine diesel engine additional motor, and to propose reasonable solutions when the vibration problem occurs, the optimization study on the modal of additional motor of marine diesel engine was carried out. The finite element model of the 200 kW motor was calculated by using the ANSYS solver. The comparison between the calculation results and the experiment results verified the validity of the finite element method, and proved that the method could provide technical support for the transient vibration analysis, noise prediction and the optimal design of the motor. |
