摘要

为满足轻型水下航行器高速航行的功率需求，提出双峰7缸新型凸轮活塞发动机设计方案。在满足强度设计基础上，对凸轮活塞发动机的凸轮机构、缸体、配气阀、活塞等主要部件进行结构设计，确定其主要参数；加工原理样机，设计试验方案，搭建试验系统，对原理样机的性能进行测试，并对试验结果进行分析。试验结果表明：新型凸轮活塞发动机结构设计合理，材料选用正确；原理样机起动可靠，运转平稳；总功率达到92 kW，并稳定运行，成功达到大功率设计目标。

Abstract

A design scheme of a new cam engine with double crest cam and 7 cylinders is proposed to meet the power needs of a lightweight underwater vehicle. The structures and parameters of the main components in cam piston engine，such as cam，cylinder， valve mechanism and piston，are determined with considering the mechanical strength requirements. A prototype was manufactured. A test scheme was designed, and a test system was built. The performance of the prototype was tested, and the test results were analyzed. The test results show that the design scheme of high power cam piston engine is practicable, and the choice of engine materials is reasonable. The prototype is reliable in starting, and stable in operation. Shaft power of engine is up to 92 kW which achieves the goal of high power design.Key
