This article provides an overview of the status, characteristics and significance of the study of the structural vibration problems , structure optimization design theory and its application in the works . Using the finite element method , the theory of structural dynamics and large - scale finite element calculation software - ANSYS , combined with the vibration of the frame structure of the Taishan Cement Plant classifiers workshop reinforced the investigation at the scene , on the basis of the dynamic test , around how to avoid the plant structure resonance , to reduce the structural vibration amplitude structural dynamic analysis and the establishment of a large number of structural reinforcement model analysis , dynamic optimization . The main results of this paper are as follows : 1 , using the spectral analysis method to analyze the spectral characteristics of the field data , to grasp the structure of the vibration frequency of the vibration source and structural vibration law . Were established before and after the reinforcement of the finite element model and flat-slab model to study the structure of the dynamic characteristics , and explore the structure of the resonance , with reference to entity model calculations of flat-slab model stiffness correction . 3, the use measured vibration source frequency sine wave equivalent incentive model role in the structural quality points , the dynamic stiffness correction after the flat-slab model , Finally, comparing the calculation results , assess the structural damping effect . 4 , the establishment of a large number of reinforcement model , using ANSYS optimization module to optimize the analysis ; compare the design of optimal solution , considering the economic structural reinforcement , applicability , feasibility and effectiveness , choose reasonable optimization program ; sensitivity at the same time analysis , given the sensitivity curve of the typical design , provide the basis for further adjustment of the structural parameters . A comprehensive summary of the research of this article , on the subject of the further deepening of the study recommendations .
