Abstract
The present invention provides a drum of a wheel tester, which is characterized in that an outer surface of the drum has cyclic corrugations parallel to a cross section of the drum, wherein the cyclic corrugation in one cycle on the outer surface is composed of a concave arc and a convex arc, both of which are tangential in ends and equal in diameter, and one cycle is 30 to 50 mm in length and 1 to 1.5 mm in depth. The drum is easy to machine, reduced in cost, increased in friction force and suitable for simulating various road surfaces.
