Railway beam-falling-prevention functional gradient sandwich energy absorption device
The invention relates to a railway beam-falling-prevention functional gradient sandwich energy absorption device which comprises a pier and a bridge superstructure, a concrete anti-seismic stop block is arranged on the pier, and a corrugated sandwich energy absorption device is arranged around the concrete anti-seismic stop block; the corrugated interlayer energy absorption device comprises a corrugated interlayer structure, the corrugated interlayer structure comprises a high-density hard foaming polyurethane filling plate and a composite material inner plate, and two layers of composite material corrugated plates are symmetrically arranged between the high-density hard foaming polyurethane filling plate and the composite material inner plate. And a nano energy-absorbing material is filled between the two layers of composite material corrugated plates. The whole corrugated interlayer energy absorption device is made of composite materials, the composite material corrugated plates are symmetrically arranged, the composite material corrugated plates are filled with nanometer energy absorption materials, and the structure in the form can give play to the good anti-extrusion performance of the composite material corrugated plates and also has the advantages of function conversion of the nanometer energy absorption materials and the like.
本发明涉及一种铁路防落梁功能梯度三明治夹层吸能装置，包括桥墩以及桥梁上部结构，所述桥墩上设有混凝土抗震挡块，所述混凝土抗震挡块的周围布置有波纹夹层吸能装置；所述波纹夹层吸能装置包括波纹夹层结构，所述波纹夹层结构包括高密度硬质发泡聚氨酯填充板以及复合材料内板，所述高密度硬质发泡聚氨酯填充板和复合材料内板之间对称布置有两层复合材料波纹板，两层所述复合材料波纹板中间填充有纳米吸能材料。波纹夹层吸能装置整体采用复合材料制成，复合材料波纹板呈对称性布置，内部填充纳米吸能材料，这种形式的结构既能发挥复合材料波纹板良好的抗挤压性能，同时也具备由纳米吸能材料功能转换等优点。
