Dynamic Analysis of Torpedo Swashplate Engine Based on Virtual Prototype Technology

Based on the prototype technology, we establish dynamical models for different types of torpedo swashplate engines, including the engine with straight groove and static cylinder, the engine with straight groove and rotational cylinder, the engine with 8-shape groove and static cylinder, and the engine with 8-shape groove and rotational cylinder, in order to select perfect types in torpedo swashplate engine design. The dynamical performances of the different engines are simulated and analyzed by using software ADAMS. The results show that the swashplate engine with straight groove and rotational cylinder is superior to other types of engines, comprehensively considering general starting performance, self-balance characteristic, force state on key parts, and working stability. This type of swashplate engine can basically realize self-balance, and its undulation of rotational speed output is small.
