调谐质量控制

大跨度细长结构的调谐质量阻尼器（TMD）系统

桥梁、摩天大楼、楼梯、烟囱和天线等结构都可能受到风、地震、附近机器或交通的强烈振动。低固有频率和低固有阻尼是此类结构的典型特征。使用调谐质量阻尼器（TMD）系统可以显著降低这些振动。

FESTBAU工程有限公司TMD系统通过吸收和耗散振动能量来限制结构的位移。通常，它们是被动系统，由振动质量、弹簧或摆和粘滞阻尼器组成。每个设备都是为其各自的应用定制的。

为了减少大型结构的垂直振动，我们通常使用带螺纹螺旋弹簧或张力弹簧的垂直质量阻尼器。钢板弹簧和摆锤悬架用于控制水平和扭转振动。TMD系统的性能可用于新结构以及现有结构的改造。

调谐质量阻尼器（TMD）系统提供有效的振动保护，并具有以下优点：

*简单、健壮、可靠的技术

*耐磨免维护结构

*无需外部能源供应

*装配后可能调整质量减振器特性

*节省空间的结构；低总成本

除FESTBAU工程有限公司调谐质量阻尼器（TMD）系统外，我们还提供工程、装配和检查，以解决您的振动问题。

Tuned Mass Control

Tuned Mass Damper (TMD) Systems for long-span and slender structures

Structures such as bridges, skyscrapers, staircases, stacks, and antennas can all be excited to high levels of vibration from wind, earthquakes, nearby machines, or traffic. Low natural frequencies and low natural damping are typical for such structures. The use of Tuned Mass Damper (TMD) Systems can significantly reduce these vibrations. 

FESTBAU ENGINEERING CO., LTD TMD Systems limit the displacements of structures by absorbing and dissipating vibrational energy. In general, they are passive systems and consist of vibration masses, springs or pendulums and Viscodampers. Each device is custom designed for its respective application.

To reduce vertical vibrations of large structures, we generally uses vertical mass dampers with threaded coil or tension springs. Leaf springs and pendulum suspensions are used for controlling horizontal and torsional vibrations. The performance of TMD Systems can be demonstrated for new construction as well as for retrofitting  existing structures.

Tuned Mass Damper (TMD) Systems offer effective vibration protection and provide the following advantages:

*Simple, robust, and reliable technology

*Wear and maintenance-free structure

*No external energy supply required

*Adjustment of mass damper properties possible after assembly

*Space saving structure; low total costs

In addition to FESTBAU ENGINEERING CO., LTD Tuned Mass Damper (TMD) Systems, we also provides engineering, assembly, and inspection to solve your vibration problem.
