Research on Vibration Control Technologies of Torpedo Power System and Its Application

To further reduce noise level of torpedo power system, the vibration control technologies of the torpedo power system are discussed in this paper, the applications of the structural dynamics design method, the vibration isolation technology of the whole machine, the vibration suppression technology of fluid pipeline, and the assembly technique in the vibration control engineering of torpedo power system are analyzed. Moreover, the development directions of the torpedo power system vibration control field are pointed out as follows: 1) at design aspect, the previous design methods mainly for solving the structural strength and stiffness should be transformed into the design method for taking structural dynamics as traction to achieve low noise and high thrust ratio of torpedo power system; 2) at vibration isolation aspect, the previous single-point partial vibration isolation should be transformed into the vibration isolation of whole machine and the vibration suppression of the fluid pipeline; and 3) at assembly aspect, the assembly process control has increasingly become an important factor affecting the vibration performance. This study may provide theoretical reference for the development of Torpedo power system with low noise level.
