摘　　要：对于大型珩磨机的珩磨头,珩磨头的刚度大小主要依靠油石座等零件的刚度大小来衡量。文章以大型双进给珩磨头油石座为研究对象,运用ANSYS软件对直径为400mm的大型珩磨头油石座进行刚度模拟计算,在保证油石座基本尺寸不变的情况下,进行结构优化,并通过材料力学的理论计算验证其正确性,进而采用模拟计算与理论计算对比的方法,得出最佳油石座导向支柱数量为四个的结论,最终得出刚度优化方案,为大型珩磨头油石座刚度优化设计研究提供了参考。For large honing head of honing machine,the rigidity of the honing head size mainly rely on oilstone seat stiffness measured size. Based on the large double feed honing stone bridge as the research object,by using the ANSYS software to a diameter of 400 mm large honing stone stiffness simulation calculation,in guarantee under the condition of invariable oilstone seat basic size,structure optimization,and its correctness is proved by the theory of mechanics of materials,then adopt the method of simulation compared with the theoretical calculation,it is concluded that the best oilstone seat number for the four pillars of the conclusion,finally concluded that stiffness optimization scheme,for large honing stone bridge rigidity as reference for optimizing design and research.
