To study dynamic characteristics and impact damage of mining scraper under different working conditions and chain speeds, the finite element model was established of scraper system which specifications was 26×92，the dynamics characteristic of scraper wad simulated and analyzed under different working conditions and chain speeds by using transient and explicit dynamics analyse module of ANSYS Workbench，and analyzed the impact damage of scraper by nCode GlypWorks under start-up conditions, the mechanical properties of scraper were obtained under variable conditions which included both running smoothly and starting under no-load or full-load, what’s more, we could obtain the rules of influence of time course for maximum equivalent stress of scraper with different speeds, acquired the degree of damage which was caused by starting impact loading under no-load or full-load. The simulation results show that, the scraper has good mechanical and anti-impact properties, provided an universal method to research the dynamic characteristics and impact damage of scraper with different specifications.
