| 摘 要： | 摩擦学特性对发动机功效的发挥起着重要作用,对其进行分析和探讨有助于改善发动机工作性能。基于斜盘发动机基本结构,建立了其内部组件的球滚动摩擦模型和柱滚动摩擦模型,并推导了相应的滚动摩擦力和滚动摩擦系数公式。然后结合某斜盘发动机具体参数,分别计算了球滚动摩擦力、摩擦系数和柱滚动摩擦力、摩擦系数,通过对比,认为柱滚动摩擦力、摩擦系数远小于球滚动摩擦力、摩擦系数。最后分析了摩擦生热、高温环境对发动机摩擦性能的影响,并指出了下一步研究的方向。

| Abstract: | Friction property plays an important role in the operating process of engine,the analysis and discuss about friction property can help to improve the operating performance of engine.Based on the basic structure of swash-plate engine,the sphere rolling friction model and the roller rolling friction model were established,and corresponding formulae of the rolling friction force and the rolling friction coefficient were deduced.Then as an application,the exact parameters of a swash-plate engine to calculate the sphere rolling friction force,the sphere rolling friction coefficient,the roller rolling friction force and the roller rolling friction coefficient were employed.According to comparison,the results that roller rolling friction force was far less than sphere rolling friction force,and roller rolling friction coefficient was far less than sphere rolling friction coefficient were concluded. |
