摘要 针对目前润滑状态测试装置的局限性,提出一种双点接触自适应摩擦试验装置。该装置结合了摩擦因数法与接触电阻法的优点,在相对静止的双下试件上测量电阻,简化了电路的设计;利用浮动支撑机构实现加载力的平衡自动调节功能,采用自下而上的加载方式,降低了导轨与滑块之间的摩擦以及装置自重对测量的影响,试验测量方便,测试精度有保证。利用该装置研究点接触下不转速和不同载荷所对应的电阻和摩擦因数,并考察两者的变化规律。试验结果表明,摩擦因数与电阻的变化存在较强的关联性。结合Dowson润滑状态的划分方法,对点接触润滑状态进行划分,并绘制了相应的润滑状态图。结果表明,该装置可对润滑状态进行精确划分,为润滑状态研究、润滑油品质鉴定等提供一种新的思路。 Aimed at the limitations of the current lubrication state test device,a dual-point contact adaptive friction test device was proposed.The device combines the advantages of the friction coefficient method and the contact resistance method,the resistance is measured on the relatively static double lower test pieces,which simplifies the design of the circuit.The floating support mechanism is used to realize the automatic adjustment of the loading force,the bottom-up loading method is adopted to reduce the interference between the self-weight of the device and the friction on the rail slider,therefore,the test measurement is convenient and the test accuracy is guaranteed.The resistance and friction coefficient corresponding to different loads and speeds at point contact were studied on the test device,and the changing law of them is investigated.Result shows that there is a strong correlation between the friction coefficient and the change of resistance.Combined with the Dowson lubrication state classification method,the point contact lubrication state was divided,and the corresponding lubrication state diagram was drawn.It is found that the device can accurately divide the lubrication state,which provide a new idea for lubrication status research and lubricant quality identification.
