To obtain the loads on the walking support unit of a shearer during the cutting processes,a 6-order model was established by applying the theories of the classical mechanics,and the disadvantages of the model were analyzed.Aiming at the over constrained problems caused by the 4supporting points between the shearer and the scraper machine,the mechanics model for the entire shearer was proposed by using the deformation compatible equation.The loads on the left driving roller and the right driving roller were achieved by the experiments,and the loads were input into the model.The model was numerically solved by employing the successive discrimination method.The solving results show that the forces in Ydirection on the left guiding boot and the left smooth boot are as smaller than that on the right sides,the axial forces on the two guiding boots are small but the directions of them are opposite.The solving results were validated by the experiments,and the results show that the model is effective.
