The Quake-proof Analysis Of Large Cavern And The Further Development Of ANSYS

At present, the function of the finite element software has been already becoming better and approaching its perfection day by day. The CAD/CAE (Computer Aided Design/Engineering) technology has important status and function in modern industrial technological transformation and high-new technical development. The FEM and the software have played an important role in CAD technology. In order to put the latest achievement of mechanics and mathematics to good use in software engineering, here the mechanical software was developed while studying the algorithm to enable the software to solve the particular type of problem.In this paper, the viscoelastic constitutive model was customized. And based on the analysis of ANSYS9.0, the standard scheme of its localization, based on the mechanism of development language named Message Catalog, was introduced to help the non-English speaking students and engineers in using ANSYS. In chapter three, the compiling and calling of the code programmed with each kind of development languages'of ANSYS was summarized, and some key type of widgets programming was described. All this jobs are expected to do some help to the further study of the secondary development of ANSYS.The analysis to the project of Hainan large cavern's quake-proof ability was carried on. In this work, viscoelastic border was adopted for the purpose of improving the simulation precision. Structure displacement and the internal forces of lining structure were observed. By contrast with the result of D-P model, the advantages of viscoelastic model was proved.The iteration method described in document [6] was adopted at first. By the analysis to the numerical value of the iteration, the tactics of how to accelerate the convergence of the iteration was put forward. Thus the iteration time was greatly decreased, and consequently considerable computing time was saved.
