摘要
依据大挠度屈曲理论,考虑沿褶皱方向张拉应力对薄膜结构的影响,推导出了屈曲后的褶皱构形参数表达式,并结合试验结果对所得公式进行了简化.采用该公式对剪切位移载荷作用下平面张拉薄膜的屈曲现象进行分析.通过与已有文献公式以及ABAQUS数值分析结果和试验结果进行比较,从而验证了该公式的有效性和合理性.
Based on the Large Deflection Post-buckling Theory, wrinkling parameters of membranes were deduced in this paper, considering the influence of the tensile stress along the wrinkles. Then, the formulas were simplified according to the experimental results and used to analyze the buckling of a membrane under shear. The results are compared with the related documents and the numerical results of ABAQUS to verify the validity and rationality of the formulas.
