Multi-level rigidity under-rail composite vibration reduction base plate
The invention discloses a multi-level rigidity under-rail composite vibration reduction base plate which is composed of three layers of base plates including an upper elastic layer, a lower elastic layer and a middle supporting layer, and a nonlinear variable rigidity matching structure is arranged between the upper base plate and the lower base plate which are adjacent to each other. The upper elastic layer and the lower elastic layer of the under-rail composite damping base plate are made of elastic materials, and the rigidity of the middle supporting layer is larger than that of the upper elastic layer and that of the lower elastic layer. The under-rail composite vibration reduction base plate can have different coping rigidities when encountering different load impacts, a reasonable stress distribution structure is arranged in the under-rail composite vibration reduction base plate, the under-rail composite vibration reduction base plate can keep good vibration reduction performance for a long time, and the service life of the under-rail composite vibration reduction base plate is prolonged.
本发明公开了一种多级刚度轨下复合减振垫板，由上弹性层、下弹性层和中间支撑层共三层垫板构成，上下相邻垫板之间具有非线性变刚度的配合结构。所述轨下复合减振垫板上弹性层和下弹性层由弹性材料制成，中间支撑层的刚度大于上弹性层和下弹性层的刚度。该轨下复合减振垫板能够在遭遇不同载荷冲击时具有不同的应对刚度，内部具有合理的受力分配结构，能够使轨下垫板长期保持良好的减振性能并延长使用寿命。
