摘要
采用自行研制的耦合变形的摩擦试验机,研究了热镀锌DC54钢带与淬回火处理的DC53冷作模具钢对偶滑块在耦合变形条件下的摩擦磨损行为,并用有限元分析了耦合变形的摩擦条件下钢带沿厚向和摩擦面的应力分布.结果表明,在耦合变形的摩擦条件下,塑性变形是影响钢带摩擦行为的主要因素,随载荷的增加,镀锌钢带与滑块间的摩擦因数增大,磨损越剧烈.
Frictional wear behavior under the condition of friction coupling with deformation between a DC54 hot-dipped galvanized steel strip and a sliding block made of quench tempering DC53 cold-work die steel was studied on a self-made tester of friction coupling with deformation.Stress distributions along the thickness direction and the rubbing surface of the DC54 hot-dipped galvanized steel strip were calculated by a finite element method.The results showed plastic deformation was the key effect factor of frictional wear behavior under this test condition.With increasing load,friction between the strip and the sliding block increased and the wear got severer.
