【摘要】 为了研究机车柴油机缸套活塞环材料的摩擦学性能，我们设计并制造了一台往复式摩擦磨损试验机。该试验机可在一定范围内实行负荷、速度,机油量的单因素控制，并可同时定性和定量地显示运动中的摩擦力大小．我们利用该试验机对美国GE公司采用的软氮化铸铁缸套-表面镀铬铸铁活塞环材料进行了摩擦学性能的试验研究，得出了该配对副在往复滑动中摩擦系数随负荷和速度变化的关系曲线．更多还原

【Abstract】 To myes t igate the tribological performance of locomotive diesel engine’scylinder liner-piston riug materials, a reciprocatiug tribology tester has been designand butilt. This e-cperimental set-up can, within a certain range, exercise control overindividual factors of load, speed and luboil quantily, and can also display, qualitativelyand quantitatively, the magnitude of friction in motion. Through myestigation on thetribological performance of soft-nitrided cast iron cylimder liner and chrome-platedcast ison piston riug materlais employed by GE company of America, a dependance offrict ion factor on load and speed has been obtained for the paired parts during theirmotion.更多还原
