Vibration Design of a Resonance Type Mixer

초록

A resonance-type mixer is a mixing device that exploits resonance, and is required in the field of fine chemicals. However, the severe vibrations associated with the resonance shorten the service life and reduce the product value. In this study, a design method is proposed for a resonance-type mixer to reduce the vibration of the driving part and to insulate the transmission of the vibration to the outside, while satisfying the vibration level necessary for mixing. According to the conditions required by the market, the mixing part generates the acceleration amplitude of 100 g at 60 Hz, and the vibration of the motor driving part is designed at 0.2 times of the mixing part. The minimum driving force condition that implements this vibration condition is obtained. It is also designed to minimize the force transmitted to the body. Finally, the validity of the theoretical analysis result is evaluated by examining the mode shape and frequency response of the mixer model through finite element analysis.
