The principle of ductwork blast gate damper

Ductwork blast gate damper generally refers to hindering the relative motion of objects, and effectively converting the generated motion friction energy into required heat energy or other functions that can dissipate energy.

ductwork blast gate damper

Ductwork blast gate damper and shock absorption technology is mainly used to set damping devices in some special parts of the structure: supports, joints or connectors, floor spaces, adjacent buildings, shear walls, nodes, between main and auxiliary structures, etc. The damping device makes it produce friction, bending, torsion, shear, viscous hysteretic deformation, elastic-plastic hysteretic deformation, and viscoelastic hysteretic deformation to absorb the energy generated in the vibration input structure, so as to carry out the seismic response of the main structure. reduce, so as to effectively avoid the damage or collapse of the structure, and achieve the purpose of shock absorption control.

The ductwork blast gate damper components in the damping damping structure are basically in an elastic state, which can mainly provide a sufficiently excellent stiffness or damping to the main structure, so that the damping damping structure can effectively meet the requirements required in normal use.

Under different vibrations, the elements of the ductwork blast gate damper device can take the lead in entering the working state of dissipating energy, effectively generating greater damping, so that the energy input into the structure is dissipated in a large amount, and the dynamic response of the structure is rapidly attenuated , and there is no obvious inelastic deformation for the main structure, so as to further ensure the safety required for the structure to be used in strong earthquakes or strong winds.
