Structure Optimization Design Of A Factory Building Based On The Software ANSYS

This paper discusses current research situation, characteristic and significance of the structure vibration , as well as introducing the structure optimization development and its application in project . On the basis of scene investigation,vibration test and vibration-proof reinforcement of Taishan cement factory building ,structure vibration analysis and optimize the characteristic of structure vibration is carried on to revolve structure resonance,reduce structure vibration scope and the change of obliquely support's cross section effect to amplitude and so on by using the finite element method, structure dynamics theory and principle concerns large-scale finite element computation software- ANSYS. The main results are as follows:1,Using frequency spectrum analysis method to analyze the frequency spectrum features of scene vibration test data ,then get vibration source frequency features and structure self-vibration features.2,Researching reinforcement or unreinforcement structure's vibration features and the reason of structure resonance by establishing finite element solid model and shell model, at the same time, modifying the model refer to solid model's results.3,With the calculating tool of the powerful FEM software ANSYS, and combined with the project example, the structure's modal analysis, harmonic response analysis and transient dynamical analysis of the workshop structure were calculated and contrasted, which shows that the optimization method was feasible.4,The mass optimization of the workshop's obliquely support was studied with the optimization design module of the software ANSYS, and the problem which should be pay attention to during the designing used this module was be pointed out in this thesis.
