Design and Function Test of Diesel Engine Cylinder Liner-Piston Ring Friction and Wear Testing Machine

设计并搭建TCLPR-1缸套-活塞环摩擦磨损试验机，进行两组工况相同的试验，实时采集试验过程中缸压、缸套温度、缸套-活塞环间油膜接触电阻、平均摩擦力、曲轴转速等信息，分析缸套-活塞环摩擦副的运动情况。结果表明：缸套-活塞环在本试验机的运行工况与实际相吻合，可通过本试验机对缸套-活塞环进行摩擦磨损试验研究。
The TCLPR-1 cylinder liner-piston ring friction and wear testing machine was designed and built in this paper. Two groups of tests under the same running conditions was conducted by using this testing machine. The cylinder pressure, cylinder temperature, contact resistance of lubrication oil film between the cylinder liner and the piston ring, the average friction force and the crankshaft speed were real-timely collected to analyze the movement of the cylinder liner-piston ring. The results show that the operating condition of the cylinder liner-piston ring is coincided with the actual operation. It certified that the designed TCLPR-1 testing machine could be used to study the tribological performances of the cylinder liner-piston ring
