%X At present, topology optimization of hydraulic gate all involves two-dimensional rather than spatial scale. In view of this, the simple isotropic material with penalization (SIMP) in continuum topology optimization method is adopted to the three-dimensional topology optimization of a deep orifice radial gate. Moreover, the topology result are simulated by finite element software, and are compared with the V-shaped dual-arm structure commonly used in engineering. The optimum topology design for radial gate arms is a tree structure, with the bearing capacity of the box section built under the requirements of local stability meeting specification standards. Comparison with V-shaped structure demonstrates that the tree structure obtained by topology optimization could reduce the holistic displacement by 15.8% and cut the maximum stress by 15% yet more evenly distributed.
