阳明滩自锚式悬索桥主缆猫道计算分析

摘要

Based on the anchor suspension bridge,set up a cat road structure according to its main cable,the ansys finite element software is applied to analyze the main force component of the catwalk calculation,it is more true that the main force components,such as the cat-carrying bearing cable,the handrail and the anti-wind cable are under the most unfavorable conditions of the force situation,the analysis results show that the safety factor of the main components of the catwalk meets the specification requirement,at the same time,the calculation method is more accurate and the practical application value is high.%依托于阳明滩自锚式悬索桥,根据其主缆架设猫道构造,应用Ansys有限元软件对猫道主要受力构件进行非线性计算分析,较为真实地反应出猫道承重索、扶手索和抗风索等主要受力构件在最不利工况下的受力情况,分析结果表明猫道各主要构件安全系数满足规范要求,同时,该计算分析方法精度较高,工程实际应用价值较高.
