摘　　要：参照SAE№2摩擦试验机进行了模拟试验机的设计,并使用满足美国GM公司的DexronⅢ规格的样品进行了试验。试验结果表明,所有模拟试验均通过100h试验,试验部件无异常磨损及剥落,结束扭矩大于160N·m,最大扭矩与中点扭矩之差不超过80N·m,啮合时间在0.35～0.55s之间,除中点扭矩外,其余各项指标均符合GM公司对汽车自动传动液的要求,证明模拟试验的方法可行,重复性符合要求。The simulation testing of SAE№2 friction testing machine was studied using the sample satisfied uexronlll standard of GM company. The testing result shows that the testing sample has not exceptional abrasion and desquamation after 100 h testing, and torsion moment at the testing end exceeds 160 N .m,the difference between the most torsion moment and the midpoint torsion moment is less than 80 N .m,the mesh time is 0. 35 -0. 55 s. All index of testing is satisfied with the requirment of auto transmission fluid of GM company except the midpoint torsion moment. The testing result also shows that the simulation testing is accurate and repetition is satisfied with the requirment.
