Novel floating slab ballast bed shock absorber
The invention relates to the technical field of floating slab ballast beds, in particular to a novel floating slab ballast bed shock absorber which comprises a shock absorber body, the shock absorber body comprises an upper cover plate and a cylinder, a telescopic sleeve is fixedly connected between the upper cover plate and the cylinder, and the cylinder is filled with a damping agent. The bottom of the upper cover plate is connected with a U-shaped permanent magnet through a connecting assembly, an electromagnet is fixedly installed at the bottom of the inner wall of the barrel, an adjusting assembly is arranged in the barrel, the bottom of the U-shaped permanent magnet is fixedly connected with a plurality of damping rods, and conical spiral blades are arranged on the outer walls of the damping rods respectively. The electromagnet is used for generating repulsive force on the U-shaped permanent magnet, vibration of the upper cover plate is further reduced, the magnetic field intensity of the upper cover plate is changed by adjusting the current intensity, so that the repulsive force is adjusted, the more downward the threaded blade is, the larger the contact area with the damping agent is, the interaction between the threaded blade and the damping agent is enhanced, and the damping effect is improved. And the absorption efficiency of vibration energy is improved.
本发明涉及浮置板道床技术领域，尤其涉及一种新型浮置板道床减振器，包括减振器，所述减振器包括上盖板和筒体，所述上盖板和筒体之间固定连接有伸缩套，所述筒体的内部填充有阻尼剂，所述上盖板的底部通过连接组件连接有U型永磁体，所述筒体的内壁底部固定安装有电磁铁，所述筒体的内部设置有调节组件，所述U型永磁体的底部固定连接有多个阻尼杆，多个所述阻尼杆的外壁分别设置有锥形螺旋叶片。本发明通过利用电磁铁对U型永磁体产生斥力，进一步减少上盖板的振动，通过调节电流强度来改变其磁场强度，从而调整排斥力的大小，螺纹叶片越向下，与阻尼剂的接触面积越大，从而增强了螺纹叶片与阻尼剂之间的相互作用，提高了振动能量的吸收效率。
