Abstract

The invention provides a vehicle-road coupling dynamic environment tester, and belongs to the technical field of vehicle-road coupling testing equipment. The vehicle-road coupling dynamic environmenttester comprises a vibration table, a temperature and humidity control box, a test stand, a test piece, a test wheel and a transmission mechanism; the temperature and humidity control box is arrangedon the vibration table; the test stand is arranged on the vibration table and positioned in the temperature and humidity control box; the test stand comprises a lifting table; the test piece is arranged on the lifting table; the test wheel is in contact with the test piece and is used for moving back and forth to roll the loaded test piece; and the transmission mechanism is arranged on the test stand and is connected with the test wheel. According to the vehicle-road coupling dynamic environment tester provided by the invention, the test piece can be simultaneously applied with a vertical pressure and a vibrating force, and the vibration table can simulate a movement state of a pavement under the vehicle load excitation in the practical engineering application, so that each mechanical parameter of the pavement can be subjected to a simulated test closer to practical application, and mechanical properties of the pavement can be really and comprehensively evaluated.

Description

technical field [0001] The invention belongs to the technical field of vehicle-road coupling test equipment, and more specifically relates to a vehicle-road coupling dynamic environment test device. Background technique [0002] At present, in engineering applications, the performance verification of mechanical indicators in specific pavement design (such as pavement anti-rutting performance, elastic modulus, fatigue characteristics, etc.) is mainly carried out in the laboratory through tests specified in the specifications, such as asphalt mixture specimen beams The three-point (four-point) bending test to test its anti-fatigue characteristics, the bending test of equal-strength cantilever beam specimens to test its elastic modulus, and the tire rolling cycle to test its anti-rutting performance. The methods and technical requirements of these experiments are in Details are specified in the engineering specification. [0003] However, the road test specimens in these exper...
