本文对摩擦磨损试验机用的磨损试样尺寸设计在Skoda-Savin磨损试验机上进行了对比试验,得出在用外径φ30、厚2.8mm磨轮试验机上,采用截面为2×4mm磨损设计试样,随磨痕深度的增加,磨痕面积及单位面积接触压力不变。采用这种磨损试验方法准确、可靠、试验误差小,是一种较新的磨损试验方法。 In this paper, the friction and wear testing machine worn sample size design in the Skoda-Savin wear test machine carried out a comparative test, obtained with the outer diameter φ30, thickness 2.8mm wheel tester, the use of cross-section of 2 × 4mm wear design test sample , With the increase of the depth of wear scar, wear scar area and contact pressure per unit area unchanged. Using this wear test method is accurate, reliable, small test error, is a relatively new method of wear test.
