摘　　要：采用盘-盘型摩擦试验机(WAZAU)评测了丁基三苯基硫代磷酸酯(IR 232)含量对自动传动液(ATF)抗颤性的影响;针对JASO M349标准摩擦因数-转速(μ-v)曲线分析方法的不足,创建了摩擦因数-长磨耐久时间的(μ-t)分析方法。结果显示:IR 232对ATF抗颤性有较大影响;虽然采用JASO M349标准的μ-v曲线分析方法可以判断出IR 232添加量的优化范围,但无法准确判定油品抗颤性失效的具体时间;而采用μ-t曲线分析方法,可以准确判断出ATF油品失去抗颤性的时间;对于不同IR 232添加量的ATF A~F共6个油品,ATF C的抗颤性最优,在长磨耐久测试后65.7 h开始失去抗颤性,说明IR 232的最优添加量(w)为0.3%。The effect of the content of butyl triphenyl thiophosphate(IR 232)on the anti-shudder performance of the automatic transmission fluid(ATF)was evaluated by the disc-on-disc tribo-test-rig(WAZAU).In view of the deficiency of the friction coefficient-velocity(μ-v)curve analysis method in JASO M349 standard,the friction coefficient-friction endurance time(μ-t)curve analysis method was developed.The results showed that IR 232 had a great effect on the anti-shudder performance of ATF.Although the optimal range of IR 232 addition could be determined by using JASO standardμ-v curve analysis method,the exact time of anti-shudder performance failure could not be determined accurately.By using the method ofμ-t,the precise time when ATF lost its anti-shudder performance could be accurately determined.Among the samples ATF A-F with different dosage of IR 232,ATF C showed the best anti-shudder performance and began to lose anti-shudder performance at 65.7 h after the durability test,which indicated that the optimal dosage of IR 232 was 0.3%.
