Design and Finite Element Analysis of Large-span Plane-truss Helicopter Door:Case Study of Yao River Westward Diversion Water Project
The design of the flood control gate for Yaojienong Control Hub of Yao River Westward Diversion Wa-ter Project adopts a large-span plane-truss vertical gate with a net width of 45 m.It is difficult to fully understand the stress state of the gate by simplifying the truss vertical gate as a flat problem.The numerical simulation meth-od is used to analyze the engineering characteristics and stress state of the large-span plane-truss vertical gate structure,and compared with measured data,which can provide technical support for the structural layout and rod system design of the gate,offering a reference for the design and calculation of similar gates.
