Abstract:The application of flexible mountings on marine internal combustion engine and relevant theory are expounded. The problems of longitudinal displacement and vertical oscillation are specially discussed and what should be paid attention to and the solutions are pointed out. To meet special requirements on vibration and noise, double mountings are put forward and introduced. Various MTU versions meeting different requirements are described. Finally, active mounting which is the latest development achievement of flexible mounting is discussed.Its basic principal and structure are introduced, as well as the application results of some MTU product. |
