Intelligent Control of Advanced Stochastic Imperfections Method for Stability Analysis of Lattice Shells
摘要
Abstract
Based on the advanced stochastic imperfections method, the program of stochastic imperfections stability analysis is combined with abnormal value examination, statistical regulation of critical loads, and selection of critical design load. And an intelligent control module is developed. The distribution and parameters of critical loads can be monitored in real time. When the calculation number is large enough to reflect the statistical regulation of critical loads invariably, the whole process is stopped instantly. Examples show that the calculation number selected by the intelligent control module can reflect the statistical regulation of critical loads invariably. The calculation number and time are greatly reduced and it provides the theoretical foundation for the selection of calculation number. It is achieved that the minimum calculation number is determined in accordance with different latticed shells.关键词
