振动机械在使用中，大多应安装弹性支承，以实现 弹性振动，并减小传给地基或结构架的动载荷。这中间，振动机械工作频率与固有频率的比值，即隔振频率比是一个非常重要的参数，直接关系到隔振效果的好坏。 有资料推荐隔振频率比取值在２～１０范围内，但隔振效果的好坏和隔振? Vibration machinery in use, most should be installed elastic bearings to achieve elastic vibration and reduce the transmission to the foundation or structural dynamic load. In the middle, the ratio of working frequency to natural frequency of vibration machine, that is, the frequency of vibration isolation is a very important parameter, which is directly related to the effect of vibration isolation. Data recommended frequency than the value of 2 to 10 range, but good and bad vibration isolation and vibration isolation?
