棱锥形钢管杆的挠度计算

Deflection Calculation of Pyramid Shaped Steel Tube Pole

为满足工程需要,在广泛论证参考文献"锥形钢管杆的稳定分析"的基础上,导出一整套棱锥形钢管杆挠度计算公式。并对计算精度及其与圆锥形钢管杆力学性能作了技术分析,其结果在条件相同情况下刚度趋近。这将为棱锥形钢管杆在城市供电、通讯等方面的广泛应用,奠定新的基础。

To meet engineering needs and based on extensive reasoning of the literature called ＂Stability Analysis of Pyramid Shaped Steel Tube Pole＂, a set of formulae for pyramid shaped steel tube deflection calculation are derived. Technical analysis for computation accuracy as well as mechanical performance of cone shaped and pyramid shaped steel tube pole are also performed. Results show that under same circumstances, the stiffness approaches each other. This study establishes a new theoretical foundation for the application of pyramid shaped steel tube pole in urban power supply and communication, etc.
