To reveal the cutting and sliding dynamics behaviors and the influence law of cantilever roadheader systems, an improved D-H parameter method was adopted to construct the kinematics model of roadheader sliding motions, and the mechanism of pose parameters on the spatial morphology of cutting cross-section was clarified. A dynamics model of roadheader pose sliding was established based on the Lagrange equation, and combined with Simulink theoretical calculation and ADAMS multi-body dynamics simulation, the dynamic response characteristics of cutting poses were systematically analyzed under various working conditions such as different working slopes and coal-rock hardness. Finally, an industrial experimental platform for roadheader pose sliding was constructed. The results show that the established dynamics model of roadheader pose sliding may well reveal the pose sliding characteristics during cross-section cutting processes, where the displacement offset deviation is approximately 15%~30%, and the attitude offset errors are controlled within 10%. Through multi-dimensional analysis methods, the dynamic evolution law of cantilever roadheader cutting sliding was systematically elucidated, and a complete theoretical framework covering kinematics modeling, load calculation, and dynamic response analysis was established.
