To ensure wheel body of the hoisting sheave strength and stability condition. For the purpose of wheel body lightweighting. There are two schemes to reduce body weight.Reduce the spokes at the same time increase the ring stiffened plate, and reduce the spokes at the same time change the spokes width and thickness.The wheel body was established based on Pro/E 3D geometric model. Import the mesh in the Workbench of ANSYS software for finite element model. Statics analysis to select the optimized scheme. Establish a hoisting sheave wheel body under the actual working condition of widening the width - deformation - wheel weight relational table. Analysis to lightweight at the same time ensure that stiffness of wheel,then it can obtaine the optimal result.

In this paper, the vibration characteristics of plate and stiffened plate in the flow field are calculated by employing fluid-solid coupling method. The wet-frequency and wet-mode numerical computing results are analyzed. The influence of boundary condition, edge length ratio and depth of water on wet mode and wet frequency are studied. A mixed finite element-boundary element method is adopted in the numerical calculation, which makes the added water mass matrix calculation be limited to the liquid-solid interface. Thereby, the calculated amount is significantly reduced and the calculation efficiency is increased.

Thispaper adopts the crack line-field method to analyze finite-width stiffenedplates with central through I-type crack under uniaxial tensile loading. Themethod completely abandons the small scale yield hypothesis. The plastic stressand strain fields at crack tips and the plastic-zone length can be accurately determinedby combining with equivalent shear stress of Westergaard stress function in theposition of stiffener. It can be seen from the illustrative example that theresults of the paper agree well with those by finite element method.
