【Abstract】 In order to limit the vibration level of main structure, it is suggested to give integrated consideration of hull-engine-propeller relationship in the concept design stage. This paper presents an example to illustrate such a design philosophy. A shallow draft full vessel is chosen, the response of its main hull strueture and superstructure to the excitations induced by the main engine and that of propeller are estimated respectively, precaution against serious vibration is done by proper choice of engine type as well as the size and speed of propeller.更多还原
