| 目的 研发用于某运输容器的减震器，同时探究减震器尺寸和填充材料的分散性对减震器设计的影响。方法 开展减震器尺寸对运输容器减震效果的分析计算，通过木材抗压强度试验获取木材压缩强度分散性，并使用有限元方法对运输容器进行9 m过重心角跌落分析，并进行9 m过重心角跌落测试验证。结果 一般来说减震器尺寸越大，其吸收能量越多，但其尺寸超过某临界点后减震效果反而下降;低抗压强度的填充木材吸能力不如较高抗压强度的，但填充木材抗压强度较大时，减震器偏硬会导致较大的容器刚体加速度。结论 该减震器设计合理，满足规范要求。填充木材的力学性能分散性，偏大或偏小都会对设计产生影响，因此，使用木材作为缓冲填充材料，设计时需要充分考虑木材压缩强度分散性对缓冲效果的影响。 |

| The work aims to develop a shock absorber for a transport cask and investigate the effects of the size of the shock absorber and the dispersion of the filling material on the design of the shock absorber. The effect of shock absorber size on the damping effect of the transport cask was analyzed and calculated. The dispersion of wood compression strength was obtained by compressive strength test of wood, and the 9 m over center of gravity angle drop analysis of the transport container was carried out through the finite element method. And the 9 m over center of gravity angle drop test was carried out for verification.Generally speaking, the larger the size of the shock absorber, the more energy it absorbed; but if its size exceeded a certain point, the damping effect decreased instead. The filling wood of low compressive strength absorbed less energy than that of high compressive strength. But when the compressive strength of the filling wood was large, the rigid shock absorber would lead to the peak acceleration of the rigid cask body. The shock absorber is well designed and meets the specification requirements. The mechanical property dispersion of the filling wood will have an impact on the design. Therefore, with the use of wood as a cushioning and shock absorption filling material, the impact of wood compressive strength dispersion of the cushioning effect should be considered. |
