The invention discloses a vibration absorption, energy consumption and vibration reduction base plate, and relates to the technical field of railway tracks. The base plate assembly comprises a base plate body, an inner plate and an elastic piece, a first through hole is formed in the middle of the base plate body, and the inner plate is arranged in the first through hole; the base plate body is connected with the inner plate through the elastic piece; the base plate body is made of rubber elastic materials, and the inner plate is made of metal materials. The elastic piece is made of a polyester elastic material; one end of the elastic piece is connected with the inner side of the first through hole, the other end of the elastic piece is connected with the side face of the inner plate, and the inner plate is parallel to the base plate body; according to the scheme, the base plate body made of the rubber material and the inner plate made of the metal material form the layered periodic structure, high-frequency vibration is controlled through the Bragg band gap, the base plate body and the inner plate are combined, and the good control effect on medium-frequency vibration and high-frequency vibration is achieved.
本发明公开了一种吸振耗能减振垫板，涉及铁路轨道技术领域，包括垫板组件；所述垫板组件包括垫板本体、内板和弹性件，所述垫板本体中部开有第一通孔，所述内板设于所述第一通孔内；所述垫板本体通过弹性件和内板连接；所述垫板本体采用橡胶类弹性材料制成，所述内板采用金属类材料制成；所述弹性件采用聚酯类弹性材料制成；所述弹性件一端和所述第一通孔内侧连接，所述弹性件另一端和所述内板侧面连接，所述内板和所述垫板本体相互平行；采用本方案，通过橡胶材质的垫板本体，以及金属材质的内板形成层状周期结构，利用布拉格带隙控制高频振动，且两者相互组合，对中、高频振动均具有较好的控制效果。
