The current standard abrasion resistance test methods of lubricating oils are based on a fixed speed and load. A new test method of lubricating oil abrasion resistance under the variable speed load test conditions was put forward, and compared with the standard test methods of SH/T 0189-92. The experimental result shows that the two methods show good consistency in the test result of lubricating oil abrasion resistance. Compared with the test method of lubricating oils abra- sion resistance of SH/T 0189-92 ,this method can shorten the test time of lubricating oil abrasion resistance, and improve the experimental efficiency. It can be used for the study of the lubricating oil abrasion resistance.目前标准的润滑油抗磨性测试方法都是在固定的转速和负荷下进行的。提出一种新的基于变速变负荷条件下的润滑油抗磨性测试方法，并与SH／T0189-92方法进行比较。结果表明，2种方法得到的润滑油抗磨性能测试结果具有较好的一致性。基于变速变负荷条件的润滑油抗磨性测试方法可缩短试验时间，提高试验效率，可用于润滑油抗磨性的试验研究。
