Cutting Characteristics of Flexible Joint Key Structure Based on Finite Element Method

Abstract

According to the characteristics of small thickness, low rigidity and easy deformation for the thin-walled structure of flexible joint, the geometric and material constitutive models of flexible joint Thin-walled structure based on the ABAQUS software were established. And the numerical simulation and data analysis were carried out through the orthogonal experiment method. The influence of different cutting parameters on the cutting characteristics of Thin-walled structures was discussed. The prediction model of deformation is consistent with the cutting parameters of the Thin-walled structure. Experiments results show that the most considerable deformation of the Thin-walled structure was not the thinnest point of the Thin-walled structure, but the place where close to the Thin-walled structure in the thin-wall processing direction. This model provides the foundation for cutting process simulation and process optimization.
