Analysis demonstrates load checking of hydraulic cylinders in double-hanging-point gates, highlighting the importance of safety assessments.
In water conservancy, the safe operation of hydraulic cylinders in double-hanging-point radial gate hoists is critical. This study proposes an ANSYS-based FSI method for load checking. SolidWorks models of gates and water are imported into ANSYS Workbench to build an FSI finite element model with hexahedral meshes. Simulations under 5 m/s flow and 1 m opening show max gate deformation (0.02 m), strain (0.0013), and stress (240 MPa), within steel limits. The hydraulic cylinder exhibits 0.2% strain and 180 MPa stress at 5s, well below load limits. The method models environmental parameters and load distribution for safety assessment. High-stiffness materials are recommended to strengthen weak cylinder parts for complex conditions.
