摘要
面齿轮精密磨削加工技术是制约其进一步发展的关键问题。通过研究专用面齿轮磨削展成加工的运动特点,以残余应力为参数指标,基于Abaqus有限元分析软件,进行面齿轮磨削数值分析。通过仿真过程分析,确定磨削仿真的可靠性;根据正交分析结果和规律探索结果,得到了磨削速度、展成速度、切深及粒度对残余应力的影响规律。具有针对性的分析结果可靠性高,为面齿轮磨削加工中的砂轮选型及参数选择奠定了理论基础。
The precision grinding technology of face gear is a key difficulty to its further development. According to study the characteristics of the special grinding generative movement of face gear,the numerical analysis of face gear grinding process is studied based on the software of ABAQUS and taking the residual stress as parameter index. The reliability of grinding simulation is determined through the analysis of simulation process.According to the results of the orthogonal analysis and rule explores,the influence law of the grinding velocity,feed velocity,cutting depth and grain size on the residual stress is obtained. The targeted results have high reliability,and the theoretical basis of grinding wheel selection and grinding parameters chosen for face gear grinding is established.
