Abstract: In underground coal mining, the collapse of roof strata frequently causes severe impact damage to advanced hydraulic supports, leading to equipment failure, production delays, and significant safety risks. To address these challenges, this study proposes a novel anti-impact device integrated with functionally graded porous structures, aiming to absorb impact energy and extend the response time of hydraulic support safety valves beyond 60 ms. The core energy-absorbing component utilizes chiral honeycomb structures with negative Poisson's ratios, characterized by low density, high stiffness, and tunable energy absorption. Numerical simulations via finite element analysis (FEA) were conducted to evaluate the dynamic impact resistance of nylon and fiberglass reinforced plastic (FRP) materials under medium-energy impacts (1×104–1×105 J). Results demonstrate that nylon exhibits greater deformation but comparable energy absorption efficiency to FRP. The findings provide critical insights into material selection for impact-resistant hydraulic supports, balancing structural integrity and energy dissipation.
