Abstract: A method and system for inversion of tire material parameters for wheel performance simulation. Based on a plurality of sets of test data obtained through tire radial rigidity and lateral rigidity tests, a tire radial rigidity and lateral rigidity test finite element simulation model is established, and error calculation is performed by comparing simulation results; and then the tire material parameters are optimized by optimizing a platform and combining results of error analysis, and a simulation process is circulated until the error is minimal, which is fitting of a test curve and a simulation curve. By using a neural network model, rapid inversion of the tire material parameters may be realized by using the neural network model only through non-destructive tire rigidity test data. The tire material parameters may be modified according to a large deformation process of a tire in a 90-degree impact test of a wheel.

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.
