摘要

大型齿圈成形磨是保证齿圈加工质量的关键工艺,成形磨削时会产生磨削力及大量热,引起磨削变形。借助工程软件Hypermesh、Matlab和ANSYS,基于磨削接触区域模型、磨削力模型和磨削移动热源理论,分析了齿圈成形磨热力作用下的变形预测仿真流程。以某大型齿圈为对象,计算了磨削区域、磨削力和热流率,建立了齿圈成形磨削有限元模型,得到了齿圈成形磨削温度场以及变形场的数值仿真云图,实现了齿圈成形磨削加工温度场以及变形的预测分析,对提高齿圈成形磨削加工精度具有一定的指导意义。

Abstract

Large gear ring forming grinding is the key technology to ensure the quality of ring gear processing. Forming grinding will produce grinding force and a lot of heat,causing grinding deformation. With the help of the engineering software Hypermesh,Matlab and ANSYS,based on the grinding contact area model,the grinding force model and the grinding and moving heat source theory,the simulation process of deformation prediction under the action of gear ring grinding is analyzed. Taking the large gear ring as an example,the grinding area,the grinding force and the heat flow rate are calculated,and the finite element model of the forming grinding of the gear ring is established. The numerical simulation of the grinding field and the deformation field of the gear ring are obtained. The prediction of temperature field and deformation of gear ring forming grinding process has certain guiding significance to improve the machining precision of gear ring forming.
