针对葛洲坝二江电站小机组改造设计后的排沙底孔工作门,在吊耳高度加高1m,废弃原有抓梁定位方式,利用门机自动抓梁的前后导向装置、侧导轮及吊耳板定位的条件下,按照《水利水电工程钢闸门设计规范》,采用大型有限元软件ANSYS进行了三维线弹性有限元分析,从强度和刚度方面进行了评价,为该工作门的改造设计提供了重要的参考依据.
Aiming at the design of small unit of Gezhouba Erjiang Power Station, the design of the bottom of the sand bottom discharge work door, in the lifting loft height increased 1m, abandon the original positioning method of the grab beam, the use of door machine automatically grab the beam before and after the guide device, side guide wheel and the hanging Under the conditions of the ear plate positioning, according to the “Code for design of steel gate of water conservancy and hydropower project”, the finite element analysis software ANSYS was used to conduct the three-dimensional linear elastic finite element analysis, which was evaluated from the aspects of strength and rigidity, An important reference.
