The rotating disc atomizer is a kind of atomizer with a wide range of uses. In this paper, a multi-curved disk rotating atomization device was designed, and the overall design of the device and the determination of the main structural parameters are introduced. The vibration characteristics of the device were tested at different operating frequencies of the motor. The maximum vibration displacement of the device in the radial horizontal direction is 0.308mm at 10Hz . The maximum vibration velocity is 11.9m/s at 35Hz in the radial vertical direction of the device. The maximum vibration acceleration in the vertical direction is 10.5m/s2 at 40Hz. The device has large vibration when operating at 10Hz and in the range of and 35-50Hz; and the operation is relatively stable in the range of 15-30Hz. It is recommended that the device operate within this range. The vibration of the device is obvious in the vertical direction, and the restraint in the vertical direction should be added to reduce the vibration of the device.
