The application of metal buffer damper in energy dissipation damping structure is more and more extensive, both in manufacturing technology, or in the installation method has made great progress, and is becoming mature, metal buffer damper in the woodworking field is also gradually developed and applied, the corresponding design specifications and viscous damper inspection procedures, testing methods and testing procedures are not perfect. However, with the increase of infrastructure and the popularization of basic knowledge of dampers, the application of metal buffer dampers in the field of woodworking will be more and more extensive, then, the following to understand the working principle of metal buffer dampers!

Determine the metal buffer damper

This includes determining the design parameters and styles of metal viscous dampers, as well as the number and placement of dampers.

Determine the style of shock absorber

There are many ways to install shock absorbers, even if it is the same shock absorber, if the installation method is different, the effect of shock absorbers will be different.

Working principle of metal buffer damper

The displacement of the diagonally supported damper is 8 times the cos of the interlayer displacement, so the displacement decreases, the velocity decreases, and the effect of the velocity dependent viscous damper decreases. For the upper and lower elbow brace damper, its displacement is larger than the displacement between layers, but the structure is complicated and the construction is difficult, so it is not suitable for general engineering. There are also K-type shock absorber columns, whose displacement is the same as the interlayer displacement, and its utility is fully utilized, but the structure is complex.

Metal buffer dampers can also be installed on the isolation layer, where dampers are used to enhance the energy dissipation of the isolation building, metal buffer damper devices usually provide viscous (velocity dependent) dampers, significantly improving the performance and effectiveness of the above isolation system.

Safety: The obvious effect is a reduction in dynamic displacement, with a 50% reduction observed experimentally. Correspondingly, the shear force is also reduced by the same amount, which means that the force and acceleration of the isolated structure are relatively reduced.

Economy: Some projects add viscous dampers to reduce dynamic displacement, which can indirectly reduce the cost of isolation support specifications, isolation joints and other structures and other displacements. The reduction of these system components reduces design and build costs and makes it more practical, but this requires comprehensive optimization calculations.

Functionality: Another advantage of the use of viscous dampers in the isolation layer is that in the case of limited space, more available space can be obtained by reducing the displacement of the isolation building. This is because the boundary of the property can be close to the infrared ray of the property.

In short, the softer the isolation layer is, the better the isolation effect is, but the larger the isolation displacement is. In order to control the displacement of the isolation layer and ensure good isolation effect, the velocity damper (i.e., viscous damper) is configured in the isolation layer.

In general, it is necessary to make full use of the metal buffer damper, but also to simple structure, convenient construction, the cantilever wall installation form, the metal buffer damper displacement and cross-layer displacement is the same, the speed is directly equal to the speed between the layers of the structure, and the construction is convenient, and can be poured at the same time with the beam column, this type balances the double effect of construction and design. In this paper, the design and analysis are carried out in this way.
