Abstract:

An electromagnet suspension gap prediction method was proposed based on long short-term memory （LSTM） neural network for high-speed maglev trains. Firstly， considering the aerodynamic load during the operation of high-speed maglev train， a train simulation model was established and the dynamic response of the train was calculated. Secondly， the LSTM neural network was established by PyCharm and the prediction model of the electromagnet suspension gap for high-speed maglev trains was built by taking the simulation calculation results as the sample set. Finally， the accuracy of the proposed electromagnet suspension gap prediction algorithm was verified by judging the calculation results and evaluation indexes of the prediction model.
