| | A new method of designing a four-rod rock-slider mechanism in complete static and dynamic equilibrium is presented in this paper. The parallelogram consists of a two-rod group connected with the rocker-slider. Complete equilibrium of the mechanism is achieved because of analogous proportional property and disposition of mass. The total mass of the mechanism is less than half the mass of the ordinary mechanism in general use. | | 提出了摇杆滑块四杆机构完全静平衡和完全动平衡的新方法:以二级杆组联接于机构的摇杆和连杆上组成平行四边形,应用相似比例性质和配重使机构达到完全平衡。这时机构的总质量还不到用一般方法时的一半. | | 文摘来源 | | In this paeer, the 3-D dynaMic equilibrium equation of the rigid bodysystem is derived by usins the screw theory. As an example, dynamic analysis of theparallel symmetric gear-crand-slidsr mechanianisms is deduced. In coninarison with themethods conventionally used, it is suporior in clarity and succinct. | | 本文用旋置理论导出了受空间力系作用的刚体旋量动态潜力学方程,其形式简洁,内函却十分丰富。作为一个特例用以推导平行齿轮曲柄滑块机构的动力学方程式,所得结果与传统的方法是完全一致的,且前者比后者在表达方式上夏简单、规范。 | | 文摘来源 | | Based upon the research on sliding wear mechanisms of cast iron materials underthe condition of linear contact lubricated,and used the methods of Auger energy spectroscopy(AES),X-ray photoelectron spectroscopy(XPS),transmission electron miCroscopy and X-ray diffractometer(XRD),the formation,distinguishing,constructure and breakaway of the sur- face film under boundarv lubrication have been examined.During the process of friction-wear,the defect and plastic deformation on friction surfaces are increased d... | | 在铸铁材料油润滑与线接触滑动磨损机制研究的基础上,对这种材料在边界润滑状态下表面膜的形成、识别、结构组成和导致膜破裂脱落的因素作了试验研究与考察,摩擦磨损过程中,摩擦表面在摩擦热的作用下,缺陷增多,塑性变形加剧,润滑油和空气中的氧通过扩散流动进入变形层,从而形成较厚的扩散反应膜,其主要成分是Fe3O4氧化膜.在给定的工况下,摩擦界面自动生成保护性氧化膜.摩擦磨损过程是氧化膜形成与破裂脱落的动态平衡过程,一旦这种平衡建立,系统就处于轻微的氧化磨损状态.氧化膜的破裂脱落与磨损表面层内奥氏体的大量生成密切相关 | | 文摘来源 | |   | | << 更多相关文摘 |
