Braking Force Estimation of Each Car

Generally braking performance of train sets is evaluated by stopping distance or deceleration. However, stopping distance and deceleration are performance indices established for a whole train set, and do not represent performance of each car individually. For more detailed analysis of detail braking performance, it is useful to have the braking force in each car. This paper describes a method designed to estimate the braking force in each car based on the acceleration and coupler force, by using coupling devices as force sensors. Running tests results on an 18-car freight train using the devised method showed that it was possible to estimate the braking force of each car and that the estimated value was close to the theoretical value.
