Application of finite element analysis in structural analysis and computer simulation

Abstract

Abstract In today’s highly developed technology, computer and Internet technology has seen a climax of innovation and its application areas are becoming more and more extensive. Computer simulation technology is the direction of computer development proposed in recent years, which can change our way of life to a greater extent. In order to explore the role of finite element analysis in structural analysis and computer simulation, this paper uses ANSYS finite element analysis combined with structural analysis methods and verified by computer simulation examples of welding thermal cycles. The results show that the computer simulation of the simulated temperature curve trend and the experimentally measured temperature curve is basically the same. Absolute error curve increases first and then decreases, basically at 11 s when the maximum, followed by a rapid decline, and then gradually slow down the rate of decline, and eventually converge on 200 °C or 180 °C or so. Such a computer simulation in a certain range to be able to more accurately simulate the welding temperature field, the study of welding problems is very valuable reference. For the simulation speed of computer simulation, combined with the structural analysis of finite element analysis, the running time was reduced by an average of 3.58 min, and the overall efficiency was improved by 21.81%. It shows that the FEA method can effectively reduce the running time and significantly improve the running efficiency. In summary, finite element analysis can optimize common problems in structural analysis, strengthen the analysis effect, and expand the application of computer simulation technology.
