金属材料磨损性能在不同试验机上得到的试验结果之间具有相关性。将从简易环—块磨损试验机上得到的材料承载能力值ＰＪ和试块擦伤时的磨痕宽度ｂ作为因子，利用加权平均型的模糊综合评判方法，可以预测该材料在Ｔｉｍｋｅｎ试验机上要测的承载能力值（对象）的大致范围；从而可以大大提高Ｔｉｍｋｅｎ试验的速度，实现有效地联合利用两种试验机对金属材料的磨损性能进行评判。
The wear behavior of metallic materials is correlated with the test results obtained on different testing machines. Taking the value of material carrying capacity PJ obtained from the simple ring-block abrasion testing machine and the width b of wear marks of the test block as a factor, a fuzzy comprehensive evaluation method of the weighted average type can be used to predict the material to be measured on a Timken test machine Of the carrying capacity (object) of the approximate range; which can greatly improve the Timken test speed, to achieve an effective joint use of two kinds of testing machine to evaluate the wear properties of metal materials.
