带贴板的耳板设计方法研究

Research on Design Method of Ear Plates with Stickers

摘要:

带贴板的耳板作为桥梁工程中一种常见的连接构造，其承载力的计算方法研究相对较少。为研究带贴板的耳板设计方法，结合实际工程中采用的耳板，基于现有的规范公式，通过必要的处理，提出了多种设计方法；同时，利用有限元软件ANSYS的接触分析模拟销轴耳板的连接，来验证各设计方法的可靠性。结果表明：基于《水利水电工程钢闸门设计规范》（SL 74—2019）的两种方法与有限元模拟结果吻合较好，推荐用以计算带贴板的耳板孔壁最大拉、压应力；建议采用有限元计算方法作为耳板剪切应力以及贴板周围焊缝应力的设计依据。

Abstract:

As a common connection structure in bridge engineering, there is relatively little research on the calculation method of bearing capacity for ear plates with stickers. To study the design method of ear plates with stickers, combined with the ear plates used in practical engineering, based on the existing standard formulas and through necessary treatments, the multiple design methods are proposed. Meanwhile, the connection of the pin shaft ear plate is simulated by using the contact analysis of the finite element software ANSYS to verify the reliability of each design method. The results show that the two methods based on the Design Specification for Steel Gates in Water Resources and Hydropower Engineering (SL 74-2019) are in good agreement with the finite element simulation results. It is recommended for calculating the maximum tensile and compressive stresses of the ear plate hole wall with stickers, and recommended to use the finite element calculation method as the design basis for the shear stress of the ear plate and the weld stress around the stickers.
