The sound absorber devices includes at least one sound absorber unit or at least one sound absorber assembly which is composed of a plurality of sound absorber units. The sound absorber unit is constructed into a box body in a hexahedron shape and forms a three-layer Helmholtz resonance sound absorption structure with double holes and single holes combined, and meanwhile, the sound absorber unit or the sound absorber assembly forms a structural resonance sound absorber. The double-absorption wheel air chamber sound resonance function organically combining Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.

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.
