结构振动控制的目的是消除或减少结构振动和结构噪声。一提起振动控制,人们常想到隔振,就是对结构采取有效措施,使结构与振源隔离,从而降低振动与结构噪声的传递。有二种隔振方式:一种是缩减机器工作时引起的振动对外界的传递,这也就是积极隔振。如汽车发动机采用弹性支承降低发动机运转时产生的振动向车体的传递;另一种是对结构进行防振,又称为消极隔振。如汽车悬挂系统,虽然汽车行驶时路面对汽车
The purpose of structural vibration control is to eliminate or reduce structural vibration and structural noise. When it comes to vibration control, people often think of vibration isolation, that is, taking effective measures to the structure to isolate the structure from the vibration source so as to reduce the transmission of vibration and structural noise. There are two kinds of vibration isolation methods: one is to reduce the vibration caused by the work of the machine transmission to the outside world, which is actively vibration isolation. Such as automotive engine with flexible support to reduce engine vibration generated when the transmission to the body; the other is the structure of anti-vibration, also known as passive vibration isolation. Such as car suspension system, while the car driving the road to the car
