Abstract：To enhance the anti-impact yielding performance of rockburst-resistant hydraulic supports and mitigate dynamic hazards caused by rockburst in deep coal mining,the original pre-folded energy-absorbing component is reinforced into a novel structural configuration.Numerical simulations are conducted to compare the resistance variations and strain evolution of both original and reinforced components under vertical compression.The influence patterns of rib plate thickness,embedded tube thickness,and hoop thickness on energy absorption performance are systematically investigated.The NSGA-II genetic algorithm is employed for multi-objective optimization of these thickness parameters,yielding optimal dimensional configurations:rib plate thickness of 3.00 mm,embedded tube thickness of 2.45 mm,and hoop thickness of 4.31 mm.Compared to the original design,the optimized component demonstrates enhanced energy absorption performance with more stable resistance fluctuations,thereby achieving superior anti-impact yielding functionality when implemented in hydraulic supports.This study provides valuable insights for the design of anti-impact energy absorption components in rockburst prevention systems.
