摘要: 为了在鱼雷发动机的设计阶段进行正确选型, 基于虚拟样机技术, 建立了不同型式周转斜盘发动机的动力学模型, 包括静缸式直导槽发动机、转缸式直导槽发动机、静缸式“8”字导槽发动机和转缸式“8”字导槽发动机, 并运用ADAMS软件对以上型式的发动机动力学性能进行了仿真分析。仿真结果表明, 从发动机的总体启动性能、自平衡性、关键零部件之间的受力状态以及工作平稳性等方面综合考虑, 转缸式直导槽周转斜盘发动机相比较其他型式的发动机, 可基本实现自平衡, 转速输出波动不大, 在工程上应优先采用。Abstract: 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.
