摘    要:通过对内燃机油工作环境和润滑状态的研究,提出变转速试验方法来评定内燃机油的抗磨性能.该方法以四球机为试验平台,以Stribeck曲线和椭圆接触理论为依据,通过试验转速的改变来匹配不同的油膜厚度,从而在测试过程中模拟发动机的润滑状态.对11种油品的抗磨性能进行了测试,考察了变转速试验方法的相关性、重复性、区分性,并与标准方法SH/T 0189进行了比较.结果表明:变转速试验方法与SH/T 0189方法显著相关,其重复性及区分能力优于SH/T 0189方法,可用于内燃机油抗磨性能研究.

关 键 词:内燃机油    变转速    抗磨性    相关性    重复性    区分性

Abstract:A variable rotating speed method was proposed to evaluate the anti-wear properties of engine oil based on the lubricant status and work environment of internal combustion engine. This method could simulate the lubrication status of engine in the test process by changing rotating speed to match the oil film thickness. It is based on the Stribeck curve and the elliptical contact theory using a four-ball tester as the experimental platform. The anti-wear properties of eleven kinds of oil were tested and the relevance, repeatability and distinctiveness of the variable rotating speed method and SH/T 0189 method were comparatively investigated. It is found that these two methods were significantly relevant. The performance of repeatability and distinctiveness of variable rotating speed method was much better than that of SH/T 0189 method. The variable speed method may be used for the anti-wear research of engine oil.
Keywords:engine oil  variable rotate speed  anti-wear properties  relevance  repeatability  distinctiveness
