Research and Simulation of Kinematics and Dynamics of Tracked Support Equipment Based on Multi-Body Dynamics

Aiming at addressing the problems of low production efficiency and safety factors in coal mines, this study designed a new type support equipment verified its theoretical reliability through analysis driving theory. The was carried out kinematics dynamics, position coordinates prototype different times were analyzed using RPY angles, spatial coordinate system established. Then, could be solved by establishing plane equations prototype. A 14-degree-of-freedom dynamic model established to reflect longitudinal characteristics traveling mechanism prototype, differential via Lagrange equation method. Finally, stability under working conditions studied multi-body simulation technology. research results show that meets design requirements, has good reliability, realizes mechanization, automation high-efficiency safe underground production. provide effective solutions for ensuring sustainable development resources mines.
