Research and Application on Reasonable Type of Gate Arm Structure
In response to the issues of easy damage and unreasonable arrangement of the arm structure in inclined arm surface hole radial gate,the spatial system method was used to systematically study the layout type of arm structure of inclined arm surface hole radial gate.By analyzing the impact of five commonly used arm structures on strength,stiffness,stability and vibration characteristics of inclined arm surface hole radial gate structure and the arm itself,and combining with the"big data"of hydraulic metal structures,the advantages and disadvanta-ges of the gate support arm in structural design,manufacturing and processing,transportation and installation,operation and maintenance were comprehensively considered,and a reasonable structural type of the surface hole inclined arm had been provided.The influence mecha-nism of the vertical and diagonal braces on the strength,stiffness and stability of the braced arm structure was clarified.The research results are proved to be reasonable by practical engineering.
