Abstract: The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.

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.
