Design a kind of rubber isolator to reduce the force which is from the power transmission system acting on the ship. Analyze the system working principle, and build the dynamics analysis model to obtain the initial parameters of the power transmission system. The characteristics of the neoprene are described by the Mooney-Rivlin model, and the coefficients C01 and C10 of the model are obtained by fitting the experimetal data of stress and strain. On the basis of practical working status of the power transmission system, the fundmental configuration and sizes are decided firstly, and then design the optimum arithmetic, in which the variables includes the bolt preload, the sizes of the rubber elememt, the space from the frontal plate to the back plate and the maximum VON MISES stress for rubber and metal, and the stiffness of the isolator is treated as target value, and the nonlinear finite element method is used for numerical simulation. As a result, the isolator is made, and it has the optimum configuration and is fit for the demand of use and reducing vibration.
