摘要
随着液氢等新能源技术的发展,考察和研究超低温环境中润滑材料、零件本体及其涂层的摩擦学机理,以建立超低温机械零件设计理论就成为该学科领域发展的必然需求.为满足超低温摩擦学实验的需要,应用销-盘摩擦副直接浸入超低温流体的设计原理,设计了一种超低温环境摩擦学性能实验系统,它由外置驱动摩擦学实验主机、开式液氮超低温环境维持系统和摩擦力检测系统三大部分组成.系统结构简单,操作方便,适于多种特殊工况摩擦学实验.
With the development of the liquid hydrogen new energy technique, it became necessary to establish the super cryogenic machine element design theories by investigating and studying tribological mechanism of lubricating material or parts and its surface coat in the super cryogenic environment. To satisfy the super cryogenic tribological test＇ s demand, we applied the design principle of the pin - dish frction pair dipped directly into super cryogenic fluid, and a kind of the super cryogenic tribological test system was designed, Which consisted of the tribological test machine by outside driving and the open type provision system of cryogenic environment and friction force detection system. Its struction is simple and operating being convenience, and it is suitable for the tribological test in special operating mode under various environments.
