基于瑞利分布的平面磨削温度场的仿真研究
Research on Finite Element Simulation of Temperature Field Based on Rayleigh Distribution in Surface Grinding
摘要
Abstract
On the basis of Rayleigh’s probability density function of undeformed chip thickness and considering the influences of grain tips’randomness on the heat flux,the heat flux entering the workpiece was assumed to have a Rayleigh distribution,a Rayleigh distribution heat source model was developed to evaluate the temperature field in surface grinding.The FEM simulation for some typical grinding conditions were carried out by using the Rayleigh distribution heat source model,the simula-tion results were compared with those obtained from triangle heat source model and rectangle heat source model,the influences of heat source model and grinding fluid on the temperature field were in-vestigated.By comparing with experimental results,a good agreement is found between the FEM re-sults obtained from Rayleigh distribution heat source model and experimental results.关键词
