High-speed railway wheel material hardness value of about 280HB, rail material hardness value of 260HB.
Value 1.2-1.4, is the experience value, temporarily unable to find the basis, sorry.
The wheel is harder than the rail. At this point, the wheel deformation is less than the track, the wheel and rail contact surface for the surface, creep phenomenon is more obvious, not easy to slip; the other hand, the rail is harder, the contact surface is similar to the plane, wheel and rail easier to slip, and this time the wheel easier to wear to the limit The Creep of the relevant content, refer to Professor Ren Zong's "vehicle system dynamics"
