Problems solved by technology

However, there is still little research on how to apply the wire rope damper to the stretcher vibration damping system, so the damping effect it can achieve is not excellent
In addition, the damping of the wire rope shock absorber itself cannot meet the needs of energy dissipation, so additional damping and vibration reduction devices are required

Abstract

The invention provides a composite shock absorber, comprising an air spring component and a particle damping component; the air spring component includes a cover plate, a bottom plate and an air bag; the air bag is located between the cover plate and the bottom plate; the particle damping component includes Particle storage chamber, feedback spring, particle and orifice; the particle damping part is located inside the airbag, the particle storage chamber is fixed on the cover plate; the bottom plate is provided with a spring slot, and the feedback spring is fixed Between the spring card slot and the particle storage room; the particle storage room is provided with several particle storage holes, and the particles are placed in the several particle storage holes; the particle storage room is provided with There are several throttling holes that are not connected to each other and correspond to the particle holding holes one by one; each of the throttling holes only communicates with the corresponding particle holding hole. The invention has lower natural frequency, can better dissipate vibration energy and alleviate dynamic impact, and can also reduce noise while achieving the effect of damping vibration.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a composite shock absorber. Background technique [0002] Take the stretcher as an example, during the driving process of the equipment carrying personnel, the vibration of the body floor will be transmitted to the human body through the "human body-support frame" system. If the vibration intensity is too large, it will not only be harmful to the emergency work during transportation, but will also aggravate the patient's health. pain, and even exacerbate the condition. According to data, there are about 10% of patients whose condition inevitably deteriorates during transportation. [0003] The traditional vibration damping device is mainly composed of ordinary elastic or rubber components. This kind of vibration damping device has been the mainstream in the early days, but it is difficult to achieve a lower natural frequency, and the vibration damping effect is not ideal. Later, ...
