摘要: 文章提出了一個建立預緊組合結構中泡沫材料有限元模型的近似方法,,其基本過程包括:建立泡沫材料性能試驗系統(tǒng)的數(shù)值模型,調整模型中泡沫材料的某些參數(shù)值直到數(shù)值結果與相應的試驗結果非常接近,,并將這些數(shù)據(jù)應用于相關的組合結構分析中,。Abstract: For numerical simulation of pretightened combined structures with foam blocks, an approximate modeling method is proposed. The basic procedures of the method include developing a numerical simulation model of foam material property test system, adjusting some parameters in the model so that the numerical results may approach the related experimental ones, and applying the test data and adjusted data to the analysis of pertinent combined structures.
