Abstract: Regarding the impact resistance performance of energy-absorbing hydraulic support, the impact loads simulation and experimental study were conducted from the perspective of the energy-absorbing hydraulic column performance. With reference to commonly used energy-absorbing column, the Finite Element (FE) and Smoothed Particle Hydrodynamics (SPH) method was employed to establish fluid-structure coupled, fluid large deformation model for the conventional hydraulic column and energy-absorbing column, enabling numerical simulations of the hydraulic column under impact loads. Impact tests were conducted on energy-absorbing hydraulic support column, to obtain displacement response of the cylinder, which were compared with numerical simulation results. Two types of hydraulic support columns were subjected to simulated impact loads using free-falling hammers of 4.5, 7, and 10.5 t, obtaining its dynamic response The impact resistance performance of energy-absorbing hydraulic support columns is discussed based on six principles of impact protection design. Compared to ordinary pillars, the displacement of the energy-absorbing columns under the impact decreased by 16%, 23%, and 30%, separately. The maximum yielding resistance of the energy-absorbing columns decreased by 15%, 21%, and 12%. The maximum yielding velocity of the energy-absorbing device may reach 18.5 m/s and can be completely crushed within 13 m/s. Regarding yielding stiffness, it was found that the energy-absorbing columns exhibited elastic stiffness before and after deforming, while they exhibited plastic stiffness during the crushing. The natural frequency of the energy-absorbing columns during yielding process was 0, avoiding the risk of resonance between the columns and surrounding rock leading to rapid destruction. The energy-absorption capacity of the energy-absorbing device could reach 272 kJ, and the overall energy-absorption capacity of the energy-absorbing columns was 80% higher than that of ordinary columns. The process of deformation and impact resistance of energy absorbing hydraulic support columns was summarized from the four stages of impact response, the impact resistance performance was analyzed. The results showed that the maximum impact energy that the energy-absorbing columns could withstand was 2.3 times that of ordinary ones, and the allowable opening time of the pressure relief valve can be extended to twice that of ordinary hydraulic columns.
