摘要
采用有限元方法并结合ANSYS软件编制了平腕臂结构参数化分析程序,实现了对腕臂结构的分析与模拟,为制定零部件荷载标准、校核腕臂结构的可靠性和提高接触悬挂的稳定性提供了工具和手段。结合实际工程,对大秦线2亿吨扩能电气化配套工程中既有腕臂结构利旧的可行性进行了分析,为确定利旧原则提供了参考;对京沪高速铁路接触网支柱基础与声屏障合建方案中所采用的腕臂结构进行了参数影响分析,为合建方案的取舍提供了技术依据。
Introduces the compiling of horizontal type cantilever structure parametrization analysis program by finite element method combined with ANSYS software. This program realizes the analysis and simulation of cantilever structure and simultaneously provides the tools and methods to establish load standard of components and to check the reliability of cantilever structure as well as to improve the stability of OCS suspension. With reference to actual construction of project, analyzes the feasibility of taking advantage of the existing cantilever structure of Datong-Qinhuangdao railway 200-million-ton heavy load electrification renovation project, providing a reference to determine the principle of taking advantage of the existing cantilever. Also carries out the parameter influence analysis of the cantilever structure adopted in the combination building scheme of OCS mast foundation and noise barrier layer in Beijing-Shanghai high speed railway, and provides the technical basis whether to use the combination building scheme.
