Research on bulldozing effect and adhesion performance model of track shoe

In order to improve the adhesion performance of track shoes on soft soil ground, analyze the components and influencing factors of track shoe adhesion, research the theoretical model of track shoe and soft ground adhesion based on the classical soil mechanics theory, and consider the influence of bulldozing effect on the coupling effect of track shoe and ground, conduct in-depth research on the bulldozing effect mechanism of track shoe in the traction process, further complete the theoretical model of track shoe adhesion, and use different types of track shoe to carry out track shoe soil groove traction test to verify the accuracy of the theoretical model. The research results show that the track shoe adhesion model established after considering the bulldozing effect and shear displacement is more in line with the actual working conditions of the track shoe soil groove traction test. The accuracy of the improved theoretical model in predicting the maximum adhesion of track shoes under three load cases is increased by 30%~41%, and the accuracy of the model under comprehensive conditions is increased by 38.10%.
