摘要：Finite element model of the main building of Zhaoguan coal preparation plant was established and its modal analysis was carried out based on ANSYS. The front six orders natural frequencies and modal shapes were calculated and the vibration characteristics were carried out. Results of modal analysis showed that the front six orders natural frequencies of the main building are between 1.7252 Hz to 5.1332Hz, which are far less than the working frequency of vibrating screen 15 Hz, so that the resonance phenomenon would not exist in the main building of the coal preparation plant.
