Wear State Research of Heavy Vehicle Based on Oil Spectrum Analysis

In this paper, spectrum analysis is conducted on wear elements in lubricating oil of a heavy vehicle to study the wear conditions. The wear elements in lubrication oil of the heavy vehicle’s transmission system were analyzed, and the evaluation value of wearied vehicle is calculated by processing spectrum data using fuzzy set theory. The two-dimensional concentration gradient model of the vehicle’s wear and tear state is obtained. The method provides the basis for understanding and judging wear action and fault diagnosis of the vehicle intelligently.
