摘要

摘要: 传统的活塞式摆盘发动机由于和摆盘连接处的受力和约束条件的复杂性, 都没有从根本上解决此处振动噪声过大的问题, 为了降低鱼雷发动机噪音, 提出了一种新型柱塞式摆盘发动机。介绍了该新型发动机的基本结构与工作原理, 分析了其力学特性, 包括柱塞相对于缸体及摆盘的运动规律, 在柱塞受力分析的基础上建立了柱塞的力平衡方程, 结合柱塞式发动机的结构推导了柱塞最小含接长度与柱塞总长之比的关系式, 为新型柱塞式摆盘发动机的结构设计提供了理论依据。该发动机在摆盘上没有约束机构, 柱塞在工作过程中产生自转, 可以起到改善润滑、减小摩擦和降低噪声的作用。

Abstract: Traditional piston wobble-plate engine can not solve essentially the problem of excessive vibration noise due to the complicacy of force and restrain condition in the join with wobble-plate. To reduce the noise of torpedo engine, a new type of plunger piston wobble-plate engine is proposed in this paper. The structure and principle of the engine are introduced. The mechanical characteristics and the movement rule of plunger piston with cylinder and wobble-plate are analyzed. The force balance equation is built based on the piston force analysis, and the relationship formula between the minimum length inside the cylinder and the whole length of the piston is derived. The conclusion may provide a theoretical evidence for the design of plunger piston wobble-plate engine. There is no restraining mechanism on the wobble-plate. The autorotation of the plunger piston during working process can improve lubrication, and reduce friction and noise.
