Real Scale Test Rotor를 이용한 3점지지 밸런싱에 관한 연구

초록

This study uses a secondary liquified natural gas (LNG) high-pressure pump with a large mass motorand thin, long pump units as the experimental model. There are certain limitations in controlling the amplitudeof the pump unit with two-plane balancing considering the vibration response due to the imbalancein the conventional motor unit. Balancing techniques are required to effectively reduce the vibrationresponse due to an imbalance in the motor unit and mode of the pump unit. Therefore, in thisstudy, four sensors were added to the pump unit to consider their effects on the motor unit and modeto determine dedicated balancing techniques using the impact coefficient method after data acquisition.
