Modal Analysis for the Tower of Large Scale

Abstract:

The rocket launch tower is a kind tower of large scale which is used in many important palces, in order to counter the tower faults problems such as leaning, bulking, etc.According to the theory of multimodal analysis, mathematical modeling and simulation of vibrational mode were conducted for the tower. The paper describes how the finite element modal for steel tower is built by means of beam and shell elements by Patran, and the analysis of the tower’s dynamical characteristic, bulking phenomenon employing commercial software Patran/Nastran,show that the results are closer to the test data,providing a basis for the tower optimal design.
