Embodiment Construction
[0044]In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes the application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.
[0045]The rail vehicle anti-skid performance test method provided in this application can be applied tofigure 1 In the application environment shown. Among them, the terminal 50 and the server 60 communicate through the network. The terminal 50 obtains the initial adhesion coefficient of the rail vehicle and transmits it to the server 60. The server 60 determines that if the initial adhesion coefficient of the rail vehicle is less than the preset initial adhesion coefficient, the terminal 50 obtains the minimum sliding percentage of the rail vehicle; If the percentage meets the preset coasting condition, the braking dist...

The invention relates to a rail vehicle antiskid performance test method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring an initial adhesion coefficient of a railway vehicle, and then judging whether the initial adhesion coefficient of the railway vehicle is smaller than a preset initial adhesion coefficient or not, thereby acquiring the minimum sliding percentage of the railway vehicle; if it the minimum sliding percentage of the rail vehicle is determined to meet the preset sliding condition, acquiring the braking distance of the railway vehicle in the sliding state; and finally, if the braking distance of the railway vehicle in the sliding state is determined to meet the preset braking distance condition, acquiring the anti-skid efficiency of the railway vehicle, the anti-skid efficiency of the railway vehicle serving as the standard for evaluating the anti-skid performance of the railway vehicle. The method can be used for testing the performance of the anti-skid system of railway vehicles with different speed levels, the calculation mode of each parameter index is defined, and the excellent performance of the anti-skid system can be evaluated visually and clearly.
Description
Technical field[0001]This application relates to the technical field of anti-skid testing, and in particular to a method, device, computer equipment and storage medium for testing anti-skid performance of rail vehicles.Background technique[0002]In recent years, the share of urban rail transit in public transportation has increased. The superior characteristics of rail vehicles such as comfort and speed are more and more popular. However, external environmental factors will have a great impact on the operation of the vehicle. For example, in rainy and snowy weather, the humidity of the environment will increase, the usable adhesion of the track will be reduced, and the wheels will slip during the braking process. Wheel scratches directly affect the operation of the vehicle. Therefore, how to verify the anti-skid function of the vehicle and make a reasonable evaluation of the performance of the anti-skid system of the vehicle has become one of the important tasks in the vehicle accept...
