振动机械是利用振动原理工作的一系列设备,由于其特有的优点在各行各业中得到广泛应用,但它在工作中产生噪声是难以避免的,一般小型机噪声80￣85dB,中大型机噪声85￣95dB甚至更高。当多台振动机械在同一场所同时工作时,这一矛盾就显得异常突出。我们在设计合肥通用机械研究所订 Vibration machine is the use of vibration principle of a series of devices, because of its unique advantages in all walks of life has been widely used, but it is difficult to avoid noise in the work, the general small machine noise 80 ~ 85dB, medium and large machine noise 85 ~ 95dB or higher. When more than one vibration machinery in the same place at the same time work, this contradiction is very prominent. We are designing Hefei General Machinery Research Institute
