Ballast bed dynamic vibration absorber and manufacturing method thereof
The invention belongs to the technical field of rail transit vibration reduction, and particularly relates to a ballast bed dynamic vibration absorber and a manufacturing method thereof.The ballast bed dynamic vibration absorber comprises an elastic layer and a mass block, the elastic layer comprises a plurality of elastic bodies of a spiral structure, an upper fixing piece and a lower fixing piece, and the elastic bodies define an annular structure; the upper fixing piece and the lower fixing piece are rigidly connected to the two axial ends of the annular structure respectively; the mass block is rigidly connected to the top of the upper fixing piece, the good vibration reduction effect is achieved in the vertical direction and the horizontal direction, and the capacity of keeping the vibration reduction effect is high. According to the method, the structural precision of the elastomer can be greatly improved, the vibration reduction capacity of the dynamic vibration absorber for the ballast bed is more uniformly distributed, vibration reduction, energy consumption and service life prolonging are more facilitated, and the elasticity of the elastomer can be easily adjusted through heat treatment, so that the design requirement can be better met; and meanwhile, the assembling speed can be greatly improved when a plurality of elastic bodies are adopted, and the later replacement of each component is also facilitated.
本发明属于轨道交通减振技术领域，具体涉及一种道床动力吸振器及其制作方法，包括弹性层和质量块，弹性层包括若干螺旋结构的弹性体、上固定件和下固定件，弹性体自身合围成环状结构，上固定件和下固定件分别刚性连接于环状结构的轴向两端；质量块刚性连接于上固定件的顶部，在竖直和水平方向上均有良好的减振效果，且保持减振效果的能力较强；本方法可以将弹性体的结构精度大幅提升，使得道床动力吸振器的减振能力分布更加均匀，更有利于减振耗能和延长使用寿命，并可以通过热处理弹性体的弹性可以轻易调整，从而能够更加适配于设计需要；同时，能大大提高采用多个弹性体时的装配速度，也便于后期更换各组成部件。
