Elastic strip dynamic vibration absorber
The invention discloses an elastic strip dynamic vibration absorber, and relates to the field of railway safety. The vibration absorber comprises an elastic damping layer and a rigid layer; a first mounting hole allowing the elastic wall of an elastic strip to penetrate through is formed in the center of the elastic damping layer, the inner diameter and the outer diameter of the elastic damping layer are 15 mm and 30 mm respectively, the elastic damping layer is made of soft rubber, and the elastic modulus is 6 MPa; a second mounting hole for mounting the elastic damping layer is formed in the center of the rigid layer, the inner diameter and the outer diameter of the rigid layer are 30 mm and 45 mm respectively, and the rigid layer is made of steel; and the elastic damping layer and the rigid layer are connected through an adhesive to form a dynamic vibration absorption structure with the thickness of 10 mm. The elastic strip dynamic vibration absorber is convenient to install and low in manufacturing cost, does not affect other performance of a fastener system and the elastic strip, can serve as a good mode for restraining resonance breakage of the elastic strip, absorbs resonance energy of a structure through a spring-damping system of the elastic strip, finally consumes the resonance energy through a damping element of the vibration absorber, and belongs to a passive vibration controller.
一种弹条动力吸振器，涉及铁路安全领域，包括弹性阻尼层和刚性层；弹性阻尼层的中心位置设置有供弹条的弹壁穿过的第一安装孔，弹性阻尼层的内、外径分别为15、30mm，材料选用软橡胶，弹性模量为6MPa；刚性层的中心位置设置有供弹性阻尼层安装的第二安装孔，刚性层的内、外径分别为30、45mm，材料选用钢材；弹性阻尼层和刚性层通过粘黏剂连接，组成厚度为10mm的动力吸振结构。本发明中的弹条动力吸振器安装方便，造价低廉，且不影响扣件系统及弹条的其他性能，可作为一种较好的抑制弹条共振断裂的方式，借助自身的弹簧‑阻尼系统吸收结构的共振能量，最后通过自身的阻尼元件进行消耗，它属于被动式振动控制器。
