The Forecasting Method about the Rate of Wheel Load Reduction Based on NARX Neural Network

The rate of wheel load reduction used for assessment the safety degree of wheels due to wheel load reduction caused by the heavy and suspended the derailment, Which is one of the important indexes about the Vehicle running safety assessment. The paper presents a forecasting method about the rate of wheel load reduction based on NARX neural network, Which use NARX neural network to realize accurate modeling of rail irregularities to the rate of wheel load reduction. The experimental results show that NARX neural network can realize the accurate prediction of the rate of wheel load reduction, and show the effectiveness of the proposed method.
