摘　　要：文章以Weigang Chen简化的折叠理论为基础,构造了结构简单的帽型截面薄壁管梁的压溃模型。通过解析计算,得出渐进压溃时,该类管梁平均静态压溃力的表达式;对比了相同结构的帽型薄壁梁在渐进压溃时,其平均静态压溃力的预测值与试验值。与实验和有限元分析结果对比表明,该文预测值优于先前的预测结果。Based on the simplified folding elements theory by Weigang Chen,a simple crushing model of top hat thin-walled tube was developed.Through analysis,the analytical expression of static mean crushing force in the progressive crush was derived.Comparing with experimental and FEA data,the theoretical predictions of this paper shows better results than previous predictions.
