A study was performed on the stress characteristics of the urban emergency flood-control box—a new equipment made of polymer material. The finite element analysis method was used to study the stress, strain and deformation characteristics of the flood control box under different water retaining heights. The results show that the stress concentration area of the box is mainly appeared at the water retaining surface and the two sides; With the increase of the water retaining height, the difference of water level between inside and outside of box as well as the maximum stress and the deformation are gradually smaller. Compared with the ABS, LLDPE, HDPE and PP materials, the deformation of the flood control box with ABS material is relatively smaller under the same conditions. An optimization study was carried out on the scheme of the flood-control box. And the stress, strain and deformation of the optimization scheme under the same conditions are greatly improved. The maximum stress decreases from 16.09 MPa in the original form to 7.31 MPa in the optimized form, and the maximum deformation decreases from 0.78 cm to 0.13 cm. The mechanical characteristics of the box structure are obviously improved.

针对一种新型高分子材质的防汛应急抢险新装备———注水式城市应急防洪箱(以下简称“防洪箱”),采用有限元分析方法研究了不同材质防洪箱不同挡水高度下箱体的应力、应变和变形等特性。结果表明,箱体的应力集中区主要在迎水面和箱体两侧;随着迎水面挡水高度的增加,箱体内、外水位差的减小,箱体最大应力和最大变形逐渐减小。ABS、LLDPE、HDPE及PP四种材质中,ABS材质的防洪箱箱体在相同条件下的最大变形相对较小。在此基础上对防洪箱的结构进行了优化研究,优化方案下,箱体在同一工况下的应力、应变及变形均有较大的改善,其最大应力由原体型的16.09 MPa下降至优化体型的7.31 MPa,最大变形由0.78 cm下降至0.13 cm,箱体结构受力特性有了明显的改善。

针对一种新型高分子材质的防汛应急抢险新装备———注水式城市应急防洪箱(以下简称“防洪箱”),采用有限元分析方法研究了不同材质防洪箱不同挡水高度下箱体的应力、应变和变形等特性。结果表明,箱体的应力集中区主要在迎水面和箱体两侧;随着迎水面挡水高度的增加,箱体内、外水位差的减小,箱体最大应力和最大变形逐渐减小。ABS、LLDPE、HDPE及PP四种材质中,ABS材质的防洪箱箱体在相同条件下的最大变形相对较小。在此基础上对防洪箱的结构进行了优化研究,优化方案下,箱体在同一工况下的应力、应变及变形均有较大的改善,其最大应力由原体型的16.09 MPa下降至优化体型的7.31 MPa,最大变形由0.78 cm下降至0.13 cm,箱体结构受力特性有了明显的改善。

A study was performed on the stress characteristics of the urban emergency flood-control box—a new equipment made of polymer material. The finite element analysis method was used to study the stress, strain and deformation characteristics of the flood control box under different water retaining heights. The results show that the stress concentration area of the box is mainly appeared at the water retaining surface and the two sides; With the increase of the water retaining height, the difference of water level between inside and outside of box as well as the maximum stress and the deformation are gradually smaller. Compared with the ABS, LLDPE, HDPE and PP materials, the deformation of the flood control box with ABS material is relatively smaller under the same conditions. An optimization study was carried out on the scheme of the flood-control box. And the stress, strain and deformation of the optimization scheme under the same conditions are greatly improved. The maximum stress decreases from 16.09 MPa in the original form to 7.31 MPa in the optimized form, and the maximum deformation decreases from 0.78 cm to 0.13 cm. The mechanical characteristics of the box structure are obviously improved.
