在工业上有些情况下,振动现象是有实际益处的。在大多数情况下振动却和故障联系在一起。对于磨削、砂轮上的振动使砂轮与工件之间,产生不受欢迎的相对运动。这样的振动能产生刃痕、波纹、颠簸甚至使被磨部分的表面产生烧伤痕迹。不但工件质量受到影响,而且磨削的经济性受到损害。 In some cases in industry, the phenomenon of vibration is of practical benefit. In most cases the vibration is associated with the fault. For grinding, the vibration on the grinding wheel causes an unacceptable relative movement between the grinding wheel and the workpiece. Such vibration can produce marks, ripples, bumps and even burned parts of the surface burn marks. Not only the quality of the workpiece is affected, but also the economy of the grinding is impaired.
