Continuous Measurement of Wheel Rail Force Based on GA-LSTM
In order to reduce the systematic error in the decoupling process of lateral and vertical forces of continuous instrumented wheelsets,a continuous measurement method of wheel-rail forces based on GA-LSTM is proposed according to the principle of neural network.The study shows that compared with the method in the national standard GB/T 5599-2019,the proposed method has higher accuracy and efficiency,and the measured data of wheel-rail forces gained by the method in a domestic operating subway line verify its effectiveness.
