Modal Analysis of Shaft System of Air Separation Compressor
HAN Yan-long;Department of Mechanical Engineering,Chengde Petroleum College;
The finite element model of air separation multi-unit shaft system is established. The author makes a modal analysis for the shaft system and gets the first 20 natural frequencies and critical speeds. The first six bands formation diagrams are obtained and the shaft vibration modes and the weak parts of the structure are confirmed. This paper provides a theoretical basis for the troubleshooting and optimized design of shaft systems.
