介绍一种新的缸套活塞环模拟磨损实时监测方法,采用一种新的缸套活塞环零部件模拟磨损试验机进行缸套活塞环零部件模拟磨损试验时,活塞环弹性背压加载系统输出的载荷信号随缸套、活塞环的磨损而变化.叙述了试验机的加载方法,进而在该试验机上进行了缸套活塞环模拟磨损试验,并对试验过程中载荷随磨损时间的变化关系、缸套磨损后的表面形貌以及线性磨损量进行综合分析.实验结果表明,通过载荷信号的变化来实时监测缸套、活塞环的动态磨损,这种监测方法可有效地对缸套、活塞环的相对耐磨性进行评价,并对缸套、活塞环的综合磨损状态进行实时监测,简化了试验数据的测量.
A new method for real-time monitoring of simulated wear of cylinder liner piston rings is introduced. When a new wear test machine for cylinder liner piston ring components is used to simulate the wear test of piston ring components, the output of the piston ring elastic back pressure loading system The load signal changes with the wear of cylinder liner and piston ring.This paper describes the loading method of the testing machine, and then simulates the wear test of cylinder piston ring on the testing machine, and analyzes the relationship between load and wear time during the testing process, Cylinder wear surface morphology and linear wear after a comprehensive analysis.The experimental results show that the load signal changes in real-time monitoring cylinder liner, piston ring dynamic wear and tear, this monitoring method can be effective on the cylinder liner, piston ring Of the relative wear resistance evaluation, and the cylinder liner, piston ring wear status of real-time monitoring, simplifying the measurement of test data.
