微动对车轴钢疲劳性能的影响
Influence of fretting on the fatigue behavior of axle steel
摘要
Abstract
Considering the characteristics of the fretting damage between railway axle and wheel, the specimen of axle and hub was designed to simulate the problem of fretting damage of interference fit under rotating bending load. The blanks were cut from the special zone of the real axle, and then machined into normal fatigue specimens and fretting fatigue specimens. The fretting fatigue specimens of axle and hub were assembled by temperature different method. Then the fatigue life of the axle steel with and without fretting was obtained with the help of four point rotating bending fatigue testing machine. The result shows that the effect of fretting on the fatigue life of axle steel is remarkable, and the fracture surfaces of fretting fatigue specimens are all near the contact edge of axle and hub.关键词
