| 摘 要： | 根据索网结构和边缘支承结构共同工作且相互影响的特点，以空间直线铰接和刚接两种杆件单元模型为基础，运用子空间迭代法，讨论了不同刚度的边缘构件对索网结构动力特性的影响，分析了各结构因素对索网自振频率边缘效应的影响规律，并与模型试验结果进行了对比。

| Abstract: | In this paper, the analytical works is based on the finite elment and accounts for the interaction between the cables and the supporting structures. It makes use of the subspace iriteration method to analyse the effects of various boundary sitffness on the dynamic characteristics of cable networks. The influens of structural factors on the boundary effects of natural frequencies is presented. The results are compared with those obtained from model experiments. |
