Lightweight and structure optimization of wheel body of the large hoisting sheave

摘要

To ensure wheel body of the hoisting sheave strength and stability condition. For the purpose of wheel body light-weighting. 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.
