摘要
通过ANSYS有限元分析软件进行中承式钢桁架自锚悬索桥动力特性分析,提出较为准确的建模方法,使计算结果能满足工程分析精度要求。列出这种新桥型有代表性的振型并进行分析,为工程实践提供实用的动力性能依据。
Using ansys finite element analysis software,the dynamic characteristic of half-through steel truss self-anchorage suspension bridge is analyzed. Present the accurate modeling method, which can be satisfied for project analysis precision requirement. List the representational vibration characteristics of the new bridge type and analysis it, the result can provide practical dynamic characteristics basis for engineering practice.
