Problems solved by technology
However, due to the influence of the working environment, it is easy to cause problems such as hydraulic oil leakage caused by the aging of the sealing rubber parts, blockage of the hydraulic damping hole, and degradation of hydraulic oil performance, and it cannot effectively control low-amplitude high-frequency or high-amplitude low-frequency vibrations.
[0003]
Especially when used on rails, problems such as leakage, blockage and deterioration will seriously affect the vibration damping ability. The vibration of low-amplitude high-frequency or high-amplitude low-frequency cannot be effectively controlled to a large extent, which will reduce the comfort of people riding in the car. The cost of the damper on the track is high and the process is cumbersome

Embodiment
[0032] Such as figure 1 As shown, a track damping module based on particle damping is used to achieve vibration reduction on the track.
[0033] It includes the lower seat plate 1 and the upper top plate 2; wherein, the lower seat plate 1 and the track are hard-connected and directly fixed, and the upper top plate 2 and the object directly above the force are also hard-connected and directly fixed, that is to say, the vibration damping module of the present invention Hard connection with the force-applying object increases the force transmission effect, thereby increasing the damping force and vibration reduction effect.
[0034] It also includes a friction spring 3, which is placed between the lower seat plate 1 and the upper top plate 2; wherein, the structure of the friction spring 3 is: the friction spring 3 includes a number of inner rings 31 arranged in sequence, and a number of outer rings 32 arranged in sequence, The outer wall surface of the inner ring 31 is provided...

The invention discloses a particle damping based track module and assembly. The particle damping based track module comprises a lower seat plate, an upper top plate, a friction spring and an inner shell. The friction spring is arranged between the lower seat plate and the upper top plate; the inner shell is arranged in the internal space of the friction spring; and a height of the inner shell is smaller than a natural height of the friction spring, the inner shell is provided with a sealed space, and particles are contained in the sealed space. By using the particle damping based track module disclosed by the invention, when external vibration or impact force is transmitted to the particles through the friction spring, the friction spring and the particles jointly weaken the impact force, and vibration is greatly reduced, so that when the particle damping based track module is applied to a track, the riding comfort can be improved, the production cost is low, the process is simple, and use is convenient.
Description
technical field [0001] The invention relates to particle damping, in particular to a track damping module and component based on particle damping. Background technique [0002] The hydraulic damper has excellent vibration reduction and impact resistance performance, and the resistance provided by the hydraulic oil consumes the motion energy caused by vibration and impact to protect the safety of the equipment under harsh environmental conditions. However, due to the influence of the working environment, it is easy to cause problems such as hydraulic oil leakage caused by the aging of sealing rubber parts, blockage of hydraulic damping holes, and degradation of hydraulic oil performance, and it cannot effectively control low-amplitude high-frequency or high-amplitude low-frequency vibrations. [0003] Especially when used on rails, problems such as leakage, blockage, and deterioration will seriously affect the vibration damping ability. Low-amplitude high-frequency or high-am...
