圆锯片基体辊压适张残余应力试验与仿真研究
Experiment and Simulation Research of Residual Stress in Circular Saw Blade Matrix under Roll Tensioning
摘要
Abstract
The residual stress distribution of the body of circular sawblade after rolling tension was studied in order to guide the optimization of the process of rolling tension.The residual stress distribution of a cir-cular sawblade was calculated by the finite element analysis(FEA)method and it was also measured by the X-ray diffraction.The characteristics of the residual stress distribution the circular sawblade were summerized by comparing the experimental results and the FEA results.The results show that the radial residual stress of the body of circular sawblade after rolling tension presents a distribution trend of"low-high-low"along the radius direction;meanwhile,the tangential residual stress presents the distribution law of"positive outside and negative inside"along the radius direction.The simulation model obtained in this paper can reflect the real stress distribution conditions on both sides of the rolled-zone.关键词
