Abstract The chain transmission system is the most important system of fully mechanized working face scraper conveyor. In order to study the dynamic characteristics of scraper conveyor in the process of operating the chain transmission system, the finite element method was used to establish translational chain model, rotary chain model, and meshing contact model of chain and sprocket while the virtual prototype model was established by 3D modeling software. The contact dynamics characteristics between chain in the start working process and the meshing contact dynamics characteristics between chain and sprocket in the normal working process were analyzed by using the nonlinear finite element software LS-DYNA. The variation of acceleration between links in the start process, the stress variation, and the variation of speed, displacement and stress in the normal process of chain and sprocket meshing were obtained which provided the key design parameters for the key parts of chain wheel transmission system transient dynamics and transmission system components optimization.
