Mark, therefore structural vibration control has become the hot research direction for current field of civil engineering.Meanwhile under Vehicle Load
The controlling of vibration be also research hotspot therein.
In modern structure vibration control mode, tuned mass damper (Tuned Mass Damper, abbreviation TMD) is
Research both at home and abroad is relatively early and more effectively a kind of passive control measure of energy free, principle are: when main structure excited vibration
When, minor structure (mass block of TMD) will generate an inertia force opposite with main structure direction of vibration, so that main structure power is rung
It should decay and reach the target of vibration damping control.Since TMD simple structure, economy, effectiveness in vibration suppression are obvious, it has been widely used at present
In the vibration control of engineering structure, such as Taipei 101 mansion, the wind dynamic control of Shanghai Center Building contour level building structure.
In engineer application, TMD is only used for controlling the vibration of single direction fundamental frequency.Thus work as and needs to structure
When the vibration of multiple directions is controlled simultaneously, need to be arranged multiple mutually independent TMD devices just with control structure different directions
Vibration.However, TMD structural vibration reduction control in a feature be mass block quality it is bigger, effectiveness in vibration suppression is better.
Therefore, when carrying out structure multi-dimension vibration control using multiple mutually independent TMD devices, biggish perseverance undoubtedly is increased to structure
It carries, or even the dynamic and static properties of main structure can be seriously affected.For this purpose, not increasing or increasing on a small quantity TMD mass block quality
On the basis of, multidimensional tuned mass damper is researched and developed, engineering structure under the dynamic load functions such as high wind, vehicle, earthquake is subtracted
Vibration control is of great significance and is worth.
