Optimal Design Method of Enhanced Active Tuned Mass Damper Based on Damping Connection

Abstract

The invention provides an optimal design method for an enhancement mode active tuned mass damper based on damping connection. The method comprises the following steps of building a structure-DEATMD system model, building a structure-DEATMD system kinetic equation according to the structural kinetic principle, carrying out optimal design of vibration control on the enhancement mode active tuned mass damper based on damping connection through a genetic algorithm compared with a traditional active tuned mass damper, considering control effectiveness and damping system travel control effectiveness by referring to an optimal result, and selecting optimal combined parameters used for guiding the practical engineering design. Compared with the traditional ATMD, on the basis of ensuring that the vibration control effectiveness is not changed or slightly improved, the travel is remarkably reduced, and structural displacement response under the earthquake action is effectively controlled.

Description

technical field [0001] The invention relates to an optimal design method of an enhanced active tuned mass damper (Damp based Enhanced Active Tuned Mass Dampers, DEATMD) based on a damping connection. Background technique [0002] Earthquake is a common and sudden natural disaster, which is still very low in predictability, widely distributed and severely damaged. Once it occurs, it will cause very serious losses to human beings. In addition to direct impacts such as house damage and collapse and casualties, earthquakes can also trigger secondary disasters such as fires and diseases, causing huge safety hazards and economic losses. my country is one of the countries most severely affected by earthquake disasters in the world. [0003] The research and application of vibration control in civil engineering structures is considered to be a major breakthrough in the field of structural wind and seismic research. It breaks through the traditional structural design method, even i...

Problems solved by technology

Passive control does not require external energy, the technology is simple, the cost is low, and the performance is reliable, but the vibration reduction effect is limited

However, at the current level of technology, pure active control needs to continuously input a large amount of energy from the outside, and the setting technology of the control system is complicated and expensive, so the application in actual engineering is obviously limited.
