Abstract
The invention belongs to the technical field of wheel rail adhesion performance simulation testing, and particularly discloses an ice and snow environment wheel rail adhesion testing device and a testing method, a stable low-temperature environment can be created through a circulating refrigerating machine and a double-disc rolling testing machine refrigerating cavity, and a multipurpose hole site is reserved in the refrigerating cavity, so that test operation and data monitoring are facilitated. The snow environment can be simulated by utilizing the ultrasonic atomization device and reasonable design. Besides, the icing thickness relation model established by the invention can be used for researching the wheel-rail adhesion characteristics under different icing thicknesses based on scientific hypothesis, and a solid theoretical basis and data support are provided for improving the running safety and reliability of the train in a low-temperature ice and snow environment.
