Simulation of Dynamic Properties of Torpedo Swashplate Engine

The virtual prototype technique has been used in the engine design of torpedo over the world. The dynamic properties of the torpedo swashplate engine are simulated by using this technique in the paper. The velocity, acceleration and the applied force of the main parts of the engine are analyzed through the simulation of the engine structure and working process. The influences of the adjusting of the structural parameters on the properties, the parts strength as well as the vibration of the engine are investigated. The methods presented and the conclusions obtained in this paper are significant for the development of torpedo engine.
