薄壁圆环件装夹变形理论分析与仿真预测
Theoretical Analysis and Simulation Prediction of the Clamping Deformation for Thin-walled Ring
摘要
Abstract
Thin walled circular ring parts are widely used in centrifugal compressor equipment.In turning machining,elastic deformation occurs due to the influence of clamping force,which affects the machining accuracy of the workpiece.To explore the influence of clamping deformation on parts and ensure the operational efficiency of centrifugal compressors,a combination of theoretical analysis and finite element simulation is used to establish theoretical deformation models and finite element simulation models for thin-walled circular ring parts under four jaw chuck clamping on horizontal lathes for optimization research.By comparing the two models,it can be concluded that the deformation results of the finite element simulation model are consistent with those of the theoretical model,and it can be concluded that the radial deformation of the ordinary clamping of thin-walled circular rings is more sensitive.Based on this,two optimized clamping schemes,axial clamping and uniformly distributed radial clamping,are proposed to reduce the radial deformation of thin-walled circular parts during the machining process.Through calculation,it can be concluded that both clamping methods can effectively reduce the clamping deformation of thin-walled circular parts,providing a theoretical basis for improving the machining accuracy of thin-walled circular parts.关键词
