Basically, one damper is produced corresponding to a set of mechanical parameters, and a production unit of the damper needs to carry out customized design on a product according to the requirements of specific engineering on the parameters. After the product is standardized, a product manufacturer does not need to design and verify the product each time depending on the actual requirements of specific projects, but can meet the individual requirements of different projects by designing limited types of standardized products and strictly verifying the standardized products, and a major breakthrough in the process is to realize the adjustability of the core mechanical parameters of the standardized products.
The invention is based on the above problems, and provides a basic energy consumption unit, which divides the traditional energy consumption plate into two parts, so that the overlapping range of the upper energy consumption plate and the lower energy consumption plate can be adjusted, the total height of an energy consumption assembly can be adjusted, and the yield displacement of the basic energy consumption unit can be adjusted. In addition, the invention also provides an assembled metal damper, and the assembled metal damper can meet the requirements of different engineering projects by combining a plurality of basic energy consumption units into the assembled metal damper and realizing the adjustment of the damping force by changing the number of the basic energy consumption units, thereby obtaining the assembled metal damper which can simultaneously meet the yield displacement requirement and the damping force requirement. The aims of standardized production, assembly installation and combined use of the metal damper are achieved, and the difficulty of quality control of the damper can be greatly reduced.
