基于磁传感技术的活塞环磨损监测试验研究

Experimental Research on Monitoring Wear of Piston Ring Based on Magnetoresistive Sensors Technology

以柴油机活塞环为研究对象,采用在缸套打孔安装磁阻传感器方法,实验室条件下进行有镀层活塞环磨损的试验,研究磨损量与传感器输出电压值的对应关系,实现在线监测活塞环的磨损量。

The research of the wear of the coated piston ring was introduced under the laboratory condition. By installing the magnetoresistive sensor in a through-hole on the wall of the cylinder liner, the relationship between the wear and sensor output voltage value was analyzed. It laid the foundation of on-line monitoring for the piston rings of marine diesel engine.
