The vibration control has two main types : initiative and passivity . i use the modulation frequency tuned mass damper to control the vibration of it and adopt ansys5 . 5 to calculate the result of it 振动控制主要有主动和被动控制，我是应用被动控制的调制调频质量阻尼器进行桥机的控制。
A new type of damper using high damping rubber is designed in this paper . the characteristic of the high damping rubber and the application of the damper on cables are discussed 本文进行了高阻尼橡胶性能试验，并在此基础上，开发设计出一种简便、实用的拉索振动被动控制装置? ?高阻尼橡胶剪切型阻尼器。
The simulation result shows that the semi - active control of vehicle suspension system equipped with electrorheologic damper has better performances of suppressing the vibration than the passive control 通过仿真计算证明，采用电流变液阻尼器的半主动控制悬架系统能够获得比被动控制悬架系统更好的减振效果。
Therefore , the dynamic loads should be considered and limited in designing landing gear . the traditional landing gear is a passive system and the parameters changes may produce an unsatisfactory performance 传统的起落架缓冲器是一种被动控制系统，其参数一经选定，在飞机起降过程中就无法进行改变，因而缓冲效果不理想。
The structure vibration control offer a new approch for the seismic design for structure , hence , the study on the method of passive structure control with sma dampers has considerable value 结构振动控制技术为结构抗震设计提供了一个新途径。因此，对sma耗能器及其结构被动控制方法进行研究，有着一定的理论意义和现实价值。

Semi - active control approaches active control in the effect , but resemble passive control in control device , which structure is simple and cost of building is cheap , so it will be a vibration control system of a good developmental prospect 半主动控制的效果接近于主动控制，但控制装置却类似于被动控制装置，结构简单，造价低，是极具发展前景的振动控制系统。
Structure vibration control is a new kind of anti - earthquake technique . structural damping by energy dampers is one of effective passive control methods and can effectively reduce structure ' s wind vibration and earthquake response 结构振动控制是一种新型的抗震技术，利用耗能器进行结构减震就是一种有效的被动控制方法，能有效的减小建筑结构的风振和地震反应。
One of these methods , passive control using viscoelastic or viscous dampers , has been applied to more and more projects in the past , because they can reduce the seismic response effectively , economically and rarely need to be repaired after they are installed 其中利用粘弹性和粘滞流体阻尼器对结构进行被动控制的方法，由于其有效性、经济性和安装后不再需要维护，而被越来越多的结构设计所采用。
In recent ten years , ved ( viscoelastic damper ) , a type passive control device , is introduced in controlling seismic responses of structures . and its extensive application is ascribed to these merits : no making structures unstable , easy installation , low cost and good performance 粘弹性阻尼器是一种典型的被动控制装置，以其不会使结构系统发生不稳定，具有安装简单、造价低廉、性能优良等优点具有广泛的工程应用前景。
