针对某型汽车发动机气缸-活塞环摩擦副润滑油的选择问题,提出并建立了由试验机和软件构成的测试单元,其中软件支持测试和服务用户,用户主要是设计主体。该测试服务单元根据汽车发动机气缸-活塞环摩擦副的结构特点和在役工况,以SRV多功能摩擦磨损实验机为试验工具,通过小试样实验提取支持决策的摩擦学数据,并将这些知识存入汽车发动机基础摩擦学服务知识库的测试单元,在软件支持下进行远程知识服务。存取的数据包括两种润滑油(20#和38#)200℃下较大PV值范围内的球盘副摩擦系数和磨损量,并且给出了含结合水0.5%和1.0%时的摩擦学数据。
Aiming at the selection of the lubricating oil for the cylinder-piston ring friction of a certain type of automobile engine, a test unit consisting of a testing machine and software is proposed and established. The software supports the testing and service users, and the user is mainly the design subject. According to the structural characteristics of the friction pair of cylinder engine-piston ring and the service conditions in service, the test service unit takes the SRV multi-purpose friction and wear testing machine as the testing tool and extracts the tribological data of supporting decision-making through small sample experiments. Knowledge into the car engine tribology service knowledge base of the test unit, the software support for remote knowledge services. The data accessed included the friction coefficient and the wear amount of the ball disks in the range of the larger PV at 200 ° C for both oils (20 # and 38 #), and gave the friction at 0.5% and 1.0% of the combined water Learn data
