振动与噪声是一种复合现象,有其产生、传递、反响和消失的过程,对千差万别的各类产品用什么方法进行振动控制与噪声控制要根据具体对象来定.一般来说有四种基本途径可以对振动和噪声进行控制.1、隔振用大阻尼隔振垫把振动源与结构隔离开.例如装载机的发动机与机架之间进行阻尼隔振,目的在于减小发动机通过机架对装载机各部位的振动传递,并减小由此激发的某些另部件的共振现象.2、阻尼把机械振动转化成热能散发出去.阻尼通常是控制结构共振与结构噪声的最有效的办法.如果把阻尼与隔振结合起来使用,往往会取得更好的效果.例如,对装
Vibration and noise are a complex phenomenon, and have their production, transmission, repercussion and disappearance of the process, the vast variety of products using different methods of vibration control and noise control according to the specific object to be set .Generally, there are four basic Way vibration and noise can be controlled.1, vibration isolation with a large damping vibration isolation pad vibration source and structure.For example, the loader engine damping and vibration isolation between the chassis, the purpose is to reduce the engine through the rack Vibration transmission to various parts of the loader, and to reduce the resonance caused by some of the other components of the resonance 2. Damping the mechanical vibration into heat energy distribution Damping is usually the most effective way to control structural resonance and structural noise If the combination of damping and vibration isolation, often get better results, for example,
