摘　　要：为了深入研究龙骨结构参数对体育木地板冲击性能的影响,对不同龙骨结构、材料的体育木地板进行冲击吸收率比对分析。结果表明:体育木地板的结构对冲击吸收率有显著影响,龙骨结构的差异会导致冲击吸收率的变化,冲击点位因龙骨位置影响体育木地板的冲击吸收率。实木龙骨结构的体育木地板冲击吸收率普遍优于LVL龙骨结构。单层实木龙骨和单层LVL龙骨的平均冲击吸收率分别为56.1%和54.9%,双层实木龙骨和双层LVL龙骨的平均冲击吸收率分别为55.3%和54.4%。体育木地板龙骨上的冲击点位低于无龙骨位置的冲击点位,双层龙骨体育木地板的龙骨交叉冲击点位的冲击吸收率最低,对双层龙骨结构的冲击吸收率整体结果影响较大,龙骨结构是影响体育木地板冲击吸收率的关键因素之一。In order to investigate the influence of the structural parameters of the dragon bone on the impact performance of sports wooden flooring,a comparative analysis of the impact absorption rates of different"dragon bone"structures and materials was conducted.The results indicate that the structure of sports wooden flooring has a significant impact on the impact absorption rate,and the differences in dragon bone structures lead to changes in the impact absorption rate.The impact absorption rate of sports wooden flooring is affected by the impact location due to the location of the dragon bone.Solid wood dragon bone structures generally have better impact absorption rates than LVL dragon bone structures.The average impact absorption rates of single-layer solid wood dragon bone and single-layer LVL dragon bone are 56.1%and 54.9%,respectively.The average impact absorption rates of double-layer solid wood dragon bone and double-layer LVL dragon bone are 55.3%and 54.4%,respectively.The impact points on the dragon bones of sports wooden flooring are lower than those at no-dragon bone locations,and the impact absorption rate at the cross-impact points on double-layer dragon bone sports wooden flooring is lowest,which has a significant impact on the overall impact absorption rate of double-layer dragon bone structures.The dragon bone structure is one of the key factors influencing the impact absorption rate of sports wooden flooring.
