Abstract

The invention discloses a drum pavement simulation material with a multilayer composite structure and a preparation method thereof, and belongs to the technical field of simulation pavement materials.The simulation material comprises a surface layer, a middle layer and a bottom layer, wherein the surface layer is formed by spraying a carbon steel base material surface with a wear-resistant layer,the middle layer is a rubber layer, the bottom layer is a common carbon steel thin layer, and the wear-resistant layer is a nickel-containing tungsten carbide coating or a 7Cr13 martensitic stainlesssteel coating. The rotary drum pavement simulation material overcomes the defects that an existing rotary drum pavement simulation material only has a shape and lacks actual pavement acting force, meanwhile, the closeness between the experimental process and actual driving is improved, actual road conditions such as lateral inclination and lateral deviation are provided, and compared with an original rotary drum pavement material, the disclosed simulation material has improved test precision.

Description

technical field [0001] The invention relates to the technical field of simulated pavement materials, in particular to a drum pavement simulated material with a multilayer composite structure and a preparation method thereof. Background technique [0002] After the production of automobile tires is completed, a performance test is required, and the pavement material on the indoor test equipment has a key influence on the test during the test process. In the performance test, in order to simulate a variety of road conditions and driving conditions such as side deviation and roll, a drum test bench is generally used to simulate the road surface for testing. The drum test bench is a commonly used tire road test equipment. The simulated road surface on the surface of the drum drives the wheels to rotate, and the wheels will be tested for side deflection and roll force when simulating the turning action. The test stand relies on the friction and reaction force between the drum a...
