Tuned Mass Damper<\/h1>\n<\/div>\n<\/div>\n<\/div>\n

A Tuned Mass Damper (TMD) is a mechanical device, that you can buy at Flow Engineering, designed to add damping to a structure for a certain range of vibration frequencies. When properly designed, the extra damping will remove excessive movements<\/span> of the structure. Feel free to contact us<\/a> for more information or for your inquiry of a tuned mass damper system.<\/p>\n

The eigenfrequencies of a structure may not be known to a sufficient level of accuracy at the time that the TMDs are designed. It is then useful to define a range in which the frequency of the eigenmode to be damped is sure to reside. By designing an appropriate Tuned Mass Damper for the entire range, the need for measuring a structures eigenfrequencies before a TMD can be produced is negated.
In the case that the structure has multiple eigenfrequencies relatively near to each other, a wide range TMD may be used to add damping to several eigenmodes. Reducing the cost of the vibration damping system.<\/p>\n

Internal Damping Ratio \u03b62\u03b62<\/h2>\n

The increase in amplitude from mis-tuned internal damping can be significant. It is because of this effect that we advise changing the internal dampers at set intervals of 15 to 25 years, depending on the damper used.
Our ongoing research into maintenance free Tuned Mass Dampers has solved this issue for linear tuned mass dampers. See our solution for linear Tuned Mass Dampers: Magnovisco Linear Dampers.<\/p>\n

阻尼器频率

在设计tmd时，结构的特征频率可能没有足够的精度。然后，定义一个需要阻尼的特征模态的频率肯定存在的范围是有用的。通过在整个范围内设计适当的调谐质量阻尼器，可以在不需要测华体会体育登录量结构特征频率的情况下设计和生产TMD。

当结构具有多个特征模态时，可以采用有效频率范围较宽的TMD为多个特征模态增加阻尼。降低减振系统的成本。

TMD阻尼比

由于内部阻尼调错，振幅的增加可能是显著的。正是由于这种影响，我们建议每隔15到25年更换一次内部阻尼器，这取决于所使用的阻尼器。
