摘　　要：汽车悬架减振系统广泛使用减振器油来提高乘坐的舒适性和平稳性。研究了一种合成减振器油。参照进口减振器油的性能,通过对基础油和添加剂的考察,研制的合成减振器油由合成烃,聚甲基丙烯酸酯黏度指数改进剂,胺型/酚型复合抗氧剂和硫/磷型抗磨剂组成。研制的合成减振器油40℃运动黏度在11.0 mm^2/s～13.0 mm^2/s之间(典型值12.3 mm^2/s),40℃运动黏度剪切下降率≤7.5%(典型值0.24%),具有良好的剪切安定性和黏度保持能力,可以提供稳定的阻尼。研制的合成减振器油通过了减振器台架试验,达到了研制目标。Shock absorber oils were widely used in automotive suspension damping systems to improve ride comfort and smoothness.A synthetic shock absorber oil was studied.With reference to the performances of imported shock absorber oils, the developed synthetic shock absorber oil consisted of synthetic hydrocarbons, polymethacrylate viscosity index improver, amine/phenolic complex antioxidants,and sulfur/phosphorus anti-wear additive through the inspection of base oils and additives.The 40 ℃ kinematic viscosity of the developed shock absorber oil was during 11.0 mm^2/s to 13.0 mm^2/s （typical value 12.3 mm^2/s）.The 40℃ kinematic shear drop rate was≤ 7.5% （typical value 0.24% ）.The shock absorber oil had good shear stability and viscosity retention and could provide stable damping. The developed synthetic shock absorber oil passed shock absorber rig test and achieved development goals.
