Dynamic Analysis of Communication Cabinet Structure Design

Abstract

Two communication cabinet finite element analysis(FEA) models with different cross-sectional structure vertical columns were set up. Based on the two communication cabinet FEA models, modal analysis was carried out by using the subspace method; the first 6 order natural frequencies and vibration modes were obtained. Harmonic response analysis was also carried out; the displacement response of the communication cabinet structure under external loading was determined. The dynamic performance comparison of the two communication cabinets with different cross-sectional structure vertical columns was performed, as a result, an effective method is provided for communication cabinet dynamic characteristic optimized design.
