Description
Technical Field
The invention belongs to the technical field of shock absorber equipment, and particularly relates to a quick return shock absorber.
Background
The damper has wide application in various equipment industries such as military and civil use. The structure is distinguished from the structure form, the rubber shock absorber and the spring shock absorber mainly comprise two categories, and in addition, in order to consider the damping effect of the system, an oil path is added in the structure to generate the damping effect. The rubber shock absorber is mainly applied to the application occasions of medium and high load and medium and high frequency, the spring shock absorber is generally applied to the occasions of low and medium frequency and low and medium load, and the hydraulic damper can improve the damping effect of a system and further reduce the vibration of the system. In summary, both rubber dampers and spring dampers have their own applications.
However, key equipment in warships and large ships has special requirements on vibration reduction: for example, a large navigator in a warship has the requirements of high rigidity, high damping and quick return on a shock absorber. Such requirements are mainly to cope with situations where strong external impacts occur (such as a sudden impact or a ballistic attack). However, the currently used rubber shock absorber or spring shock absorber does not have the characteristic of high rigidity and high damping for quick return without adding an additional damper.
