Analysis on Structural Strength of Comb Bit Based on Ansys Workbench

Abstract:

Take φ2500mm comb bit as the object, use three-dimension drawing software Solidworks to establish the three-dimension modal of the bit, apply a new generation of multi-physics field collaborative simulation environment Ansys Workbench for mesh generation and static analysis, the equivalent stress and displacement nephogram of the overall structure were got and the maximum deformation value, maximum stress value and the location of the maximum stress point of the bit under the maximum load and wing plate force condition were obtained. The data obtained are very critical to check the strength and stiffness of the bit and important in the optimization of design process.
