Floating slab track vibration isolator for track traffic
The invention provides a floating slab track vibration isolator for track traffic, which belongs to the technical field of track traffic vibration damping and comprises a steel framework serving as a main body of the vibration isolator and used for providing supporting rigidity; the rotary mass block is used for absorbing a vibrator of a load in the vertical direction borne by the vibration isolator; the rubber connecting piece is used for controlling the rotating mass block to rotate, the steel framework is of a hollow cage-shaped structure, the rotating mass block is placed in the steel framework, the rotating mass block is connected with the steel framework through the rubber connecting piece, when a vertical load caused by train operation is applied to the vibration isolator, the steel framework generates torsional deformation, and the vibration isolator is driven to rotate. And meanwhile, the rubber connecting piece drives the rotating mass block to rotate, a part of energy is transferred into the rotating mass block, and therefore vibration isolation is achieved. According to the vibration isolator, due to the fact that the vibration isolator has the additional compression-torsion coupling performance, the vibration isolator has the additional vibration isolation capacity, the structure is simple, and it is ensured that the vibration isolator has the enough bearing capacity by increasing the cross sectional area of the supporting component.
本发明提供了一种轨道交通用的浮置板轨道隔振器，属于轨道交通减振技术领域，该隔振器包括钢骨架，作为隔振器的主体，用于提供支承刚度；旋转质量块，用于吸收隔振器受到的垂直方向荷载的振子；橡胶连接件，用于控制旋转质量块作旋转运动，钢骨架为镂空式的笼状结构，旋转质量块放置于钢骨架的内部，旋转质量块通过橡胶连接件与钢骨架连接，当列车运行引起的垂向荷载施加到隔振器时，钢骨架产生扭转变形，同时橡胶连接件带动旋转质量块旋转，将一部分能量转移至旋转质量块中，以此实现隔振。本发明提供的隔振器，由于其具有额外的压扭耦合性能，进而使其具有额外的隔振能力，且结构简单，通过提高支承部件的横截面积，确保其具有足够的承载能力。
