NX17BK型称重装置车轨料动态称重装置研究
Journal: Building Technology Research DOI: 10.12238/btr.v7i4.4484
Abstract
动态称重装置采用型钢纵横梁结构与三段式拼装设计,全长10.95m,宽2.7m,标准段高10cm,支撑处净高5cm。采用Midas Gen对装置进行数值分析,结果表明：(1)装置自重4.08t,边支点承载0.5t,中支点承载0.52t；(2)满载时装置边支点承载7.8t,中支点承载8.22t,总承载64.08t；(3)满载时最大挠度为6.5mm,最大拉应力为180.9MPa,最大压应力为171.6MPa；(4)依据GB50017-17和GB50018-02规范对装置进行验算,其应力、内力、稳定性、挠度指标均满足要求。装置具有易安装、强度高、变形小、寿命长的优点,对铁路轨料安全运输具有较高的实用价值。
