Ballast bed anti-vibration pad with nonlinear rigidity
The invention discloses a ballast bed anti-vibration pad with non-linear rigidity, which comprises a base plate base body and a transverse through hole arranged in the base plate base body, and non-linear structure bulges and linear structure bulges are alternately arranged on one surface of the base plate base body. Compared with the prior art, the ballast bed anti-vibration pad has the beneficial effects that the multiple nonlinear structure protrusions and the multiple linear structure protrusions are arranged on the ballast bed anti-vibration pad alternately in rows, a certain anti-vibration and noise-reduction effect can be provided when the load is small, meanwhile, the settlement amplitude of a train is small, and the comfort of passengers is improved; when the load is large, the protrusions on the ballast bed anti-vibration pad are compressed to the maximum limit, the rigidity of the protrusions is the second-level rigidity provided by the base plate base body, the transverse through holes are formed in the base plate base body, the rigidity difference between the first-level rigidity and the second-level rigidity is reduced, and the vibration reduction effect is achieved. And the rigidity similar to that of an existing ballast bed anti-vibration pad composed of a plurality of nonlinear structure bosses can be provided.
本发明公开了一种具有非线性刚度的道床减振垫，包括垫板基体和设置在垫板基体内的横向通孔，在垫板基体的一面交替设置有非线性结构凸起和线性结构凸起。与现有技术相比，本发明的积极效果是：本发明在道床减振垫上设置若干个非线性结构凸起和若干线性结构凸起成排交替排列，载荷小时，能够提供一定的减振降噪效果，同时列车沉降幅值小，提高乘客舒适性；载荷大时，道床减振垫上的凸起被压缩至最大限度，其刚度为垫板基体提供的第二级刚度，本发明的垫板基体内设有横向通孔，降低第一级刚度与第二级刚度的刚度差，并能够提供与现有由若干个非线性结构凸台构成的道床减振垫相近的刚度。
