Measurement and Analysis of the Vibration of PP Plant Frame
摘要
Abstract
Significant vibration can be notified in the upper part of pp plant frame while operating in a petrochemical company. In order to ensure the safety of the structure and equipment, the self-vibration characteristics and vibration response of the frame structure are measured in the field. Maximum acceleration is 277 mm/ s . The excitation source is constructed by reverse engineering method. The vibration response of structure is calculated, with a very close to measured result. A plan of adding cross-bracing in the upper part is calculated. The natural frequency of structure is improved to avoid the excitation frequency band. The north-south acceleration amplitude would be reduced 76% while the east-west amplitude would be reduced 28%. The reduction of vibration is remarkable.
