| 摘 要： | 基于Carreau剪切稀化非牛顿流变模型,针对一种空间用国产氯苯基硅油(CSO)弹流牵曳特性进行了完全数值解,CSO相关流变参数值为拟合实验数据所得.采用球-盘式弹流牵曳试验装置,测定了CSO在不同工况下弹流牵曳系数.将理论与实验结果进行比较表明,随着滑滚比的增大,CSO弹流牵曳系数经历了由急剧增加到缓慢增加,直至逐渐减小的过程.与其他2种润滑油相比,CSO弹流牵曳系数对载荷敏感度低,且在大滑滚比工况下弹流牵曳系数随滚动速度增大而减小.因此,在高速重载工况下,用CSO润滑的空间摩擦学部件寿命更长,动力消耗更低.但是,CSO在宽温度范围内,粘度变化幅度为5个数量级,因此,不适合在低温工况环境下使用.

| Abstract: | Elastohydrodynamic lubrication(EHL) traction behavior of a kind of chlorphenyl silicone oil(CSO) used in spacecraft mechanisms is studied.The Carreau viscosity model is used to describe the shear-thinning behavior encountered in EHL.Rheological tests are performed in order to determine the rheological parameters of the CSO.Tribological tests are carried out on a ball-disk traction rig to measure the traction coefficient for different operating conditions.Experiments are compared with theoretical ones.It is ... |
