To detect the wheel pressure of crane accurately and conveniently,a wheel pressure test piece based on strain-wheel pressure model was developed.Based on the strain generated by the test piece under the crane wheel,a neural network model was constructed,and the strain data was introduced into the neural network for training.The trained model was used to infer wheel pressure of cranes.The experimental results show that it is feasible to detect the wheel pressure of cranes by using the neural network.
