Description

Shock absorption and energy dissipation device

technical field

The utility model relates to a shock-absorbing and energy-dissipating device, in particular to a device that is applied to various buildings or mechanical structures. When strong winds or earthquakes act on buildings or mechanical structures, a shock-absorbing device is provided. Functional person, and can be applied to civil construction, mechanical engineering and other related application fields.

Background technique

Taiwan is located at the junction of the Eurasian plate and the Philippine Sea plate. The number of earthquakes that occur every year is very frequent, and there are often strong earthquakes. When an earthquake occurs, it will affect the buildings on the ground. The damage of its energy cannot be feared. If the structure of a general building is not equipped with shock-absorbing and energy-dissipating devices, or the design concept of earthquake resistance and shock resistance is not integrated into the building, the energy generated by the earthquake will cause damage to the building, and in severe cases, the building will be damaged. Fracture collapse, for example, Taiwan had a major earthquake on September 21, 1999, that earthquake caused many people to suffer serious disasters, and also caused many buildings to collapse or half collapse. Without any shockproof design, it is easy to be directly damaged and collapsed under strong earthquakes.

Generally, the structural strength of a building can resist relatively small earthquakes or strong winds. In order to prevent the main structure of the building from being damaged by external forces and collapse, in addition to directly using the building structure to resist earthquake and strong wind energy, it is also a way to slow down these impact energies. The method of anti-shock measures.

Stiffened dampers made of metal materials have been widely used in the field of building vibration control in recent years. This type of vibration control products, combined with specially designed structure and device technology, causes the damping body to enter the plasticity of the material when the energy is transmitted. Stage, and then provide a certain amount of stiffness and toughness, the energy is absorbed and buffered by the deformation of the damper, and the energy generated by the vibration can be eliminated.

Although the known stiffening damper is quite effective in use, its design cannot effectively eliminate the energy transfer in multi-dimensional directions, and is only limited to the single-dimensional force mode. However, when an earthquake occurs, it will shake the building up and down, and its transmission force The method is generally multi-dimensional, and the known stiffening damper cannot effectively eliminate this energy; and the known jointing method of the stiffening damper and the force transmission seat is a fixed method of welding, and uneven heat input is likely to cause material instability and deformation; and it is easy to target Slight vibration resistance may easily cause metal fatigue and fracture over a long period of time, and it will not be able to maintain a balanced force, which is the key point to be considered.

Although some companies use larger damping bodies as energy dissipation devices in response to the above-mentioned situation, they are expensive to use and cannot respond immediately to small vibrations. Therefore, the known shock-controlling and energy-dissipating devices still have deficiencies that need to be improved.
