Pages 5

Among the experiment results of the DynoTRAIN project, the measurement of Y and Q forces in different curves have been corrected and used to extract a representative friction coefficient, by comparison to a model using Kalker’s approach. The result is a set of friction values from 0.23 to 0.35 observed on field in conditions considered dry, and a standard deviation to a normal law of approximately 10%.
