摘要
为满足轻型水下航行器高速航行的功率需求,提出新型凸轮发动机设计方案.对该凸轮发动机的凸轮机构、缸体和配气阀等主要部件进行结构设计,确定其主要结构参数,对发动机工作过程进行计算机仿真.仿真结果表明,该凸轮发动机在仿真工况下轴功率达114.9 kW,较MK46鱼雷的双峰5缸凸轮发动机轴功率提高了约60 kW,凸轮发动机结构设计合理且可行.该研究为深入进行发动机力学分析、仿真研究提供了必要的基础.
A new design of CAM engine was proposed to meet the power needs of a lightweight underwater vehicle. The structure and parameters of the main components in CAM engine, i.e. , CAM, cylinder, and valve mechanism, were determined. The simulation results of the working process have demostrated that the new engine axail power reaches 114.9 kW and is improved about 60 kW compared to a MK46 torpedo CAM engine with two lift and five cylinders. The design of this proposed new engine is feasible and can guide further mechanical analysis and simulation.
