Dampers made of damping are a particularly important part of hardware accessories, but how does it work? Shock absorbers are used in aerospace technology, military and other industries, and their general function is shock absorption High efficiency, and then slowly applied to construction, furniture hardware and other industries. dampers come in many forms, such as pulsation dampers, magnetorheological dampers, rotary dampers, hydraulic dampers, etc. Different damper forms may be different, but the principle is the same. In order to reduce vibration, the friction is converted into internal energy to drive the operation of the entire system.
Damper principle
Damping generally refers to hindering the relative movement of objects, effectively converting the generated friction energy into the required heat or other energy dissipation.
damping structure damping technology is generally to install damping devices in some special parts of the structure: supports, nodes or connectors, floor space, adjacent buildings, shear walls, nodes, primary and secondary structures, etc, the damping device generates friction , bending, torsion, shear, viscous hysteresis deformation, elastic-plastic hysteresis deformation, and viscoelastic hysteresis deformation to absorb the energy generated in the vibration input structure, so as to reduce the seismic response to the main structure. Process, so as to effectively avoid damage or collapse of structure, to achieve the purpose of controlling shock absorption.
Damping The damping element in the damping structure is basically in an elastic state, and generally provides sufficient stiffness or damping for the main structure, so that the damping structure can effectively meet the requirements of normal use.
Under the action of different vibrations, the components of the vibration damping device can enter the working state first to consume energy, effectively generating greater damping, dissipating a large amount of energy input to the structure, the dynamic response of the structure attenuates quickly, and the main structure has no obvious inelastic deformation, further ensuring the safety of the structure when used in strong earthquakes or strong winds.
When the solid vibrates, the energy generated when the solid vibrates is dissipated by the damping layer as much as possible. This method is called damping shock absorption.
