摘要
针对中国商飞部装厂房3万m2焊接球屋盖的整体提升施工工艺,对提升工艺中最关键的提升架和格构柱建立了整体分析模型,对整个系统的稳定性进行了计算分析。计算结果表明,格构柱最大应力仅为个别应力集中点,对柱整体没有影响。通过对细部有限元分析可以看到,有些部位应力水平较高,对这些部位通过设置加劲肋进行局部加强。
The integrated numerical model for lifting frame and latticed column is established,which are the key part of the lifting system for the COMAC installed plant with 30 000m2.The overall stability of the integrated system is analyzed.The simulation results show that the biggest stress of the latticed column is individual and has no influence on integrity.And through detailed simulation analysis,local strengthening with stiffening rib is applied on the parts with high stresses.
