Method for predicting adhesion coefficient at contact point between wheel and rail of railway vehicle, method for improving adhesion coefficient at contact point between wheel and rail of railway vehicle, and apparatus for implementing these methods

摘要

The moisture on the rail is associated with the reduction of the sticking coefficient between the rail and the rail of the railway vehicle, which may result in a safety risk or delay in the operation flow.In order to increase the adhesion coefficient as shown by the original, in the prior art, for example, the vehicle is sprayed to the rail automatically by the driver of the traction vehicle or in the danger state.The present invention provides a method for predicting the adhesion coefficient between wheels and rails by using various different parameters, such as temperature and pressure, already detected by an existing system of a railway vehicle in the self learning algorithm.Disclosed are methods for improving the adhesion coefficient and apparatus for performing the above two methods.
