Nonlinear damping vibration isolator, floating slab with nonlinear damping vibration isolator and floating slab track system
The invention discloses a non-linear damping vibration isolator, a floating slab with the nonlinear damping vibration isolator and a track system . The non-linear damping vibration isolator comprisesa fixing part and a moving part. The fixing part comprises a base, a damping cylinder part and a sleeve, and the damping cylinder part is fixed in the middle of the base; the sleeve is correspondinglypositioned outside the damping cylinder part and is fixed along the peripheral side of the base; the moving part comprises a top cover, a steel spring and a damping piston, and the top cover is located above the sleeve and movably connected with the upper end of the sleeve in a sealed mode; the steel spring is sleeved between the damping cylinder part and the sleeve, and the upper and lower endsof the steel spring correspondingly abut against the top cover and the base; one end of the damping piston is fixed with the top cover and the other end is positioned in the damping cylinder part; a damping hole is formed in a cylinder body of the damping cylinder part, the linear distance between the cylinder body and the inner wall of the sleeve is gradually changed, and damping liquid is contained in the damping cylinder part and the sleeve. The variable damping characteristic of the vibration isolator can be achieved, the resonance peak of the vibration isolator is reduced and the high-frequency load is not amplified, vibration of a roadbed slab is weakened, and meanwhile noise is lowered.
本发明公开了一种非线性阻尼隔振器及具有其的浮置板及轨道系统，包括固定部，固定部包括底座、阻尼筒部件及套筒，阻尼筒部件固定在底座中部；套筒对应位于阻尼筒部件外侧且沿底座周侧固定；运动部，运动部包括顶盖、钢弹簧及阻尼活塞，顶盖位于套筒上方且与套筒上端密封活动连接；钢弹簧套设在阻尼筒部件与套筒之间且其上下端对应与顶盖与底座抵接；阻尼活塞一端与顶盖固定，另一端位于阻尼筒部件内；阻尼筒部件的筒体上设有阻尼孔且该筒体距离套筒内壁的直线距离为渐变设置，阻尼筒部件及套筒内装有阻尼液。本发明可以实现隔振器的变阻尼特性，使得隔振器在减小共振峰的同时不放大高频载荷，削弱了道床板的振动，同时降低了噪声。
