基于有限元分析的飞刀优化设计及安全校核(英文)

Optimal design and security verification of flying cutter based on finite element analysis

汽车同步器齿套的滑块槽属难加工内表面。介绍了滑块槽加工工艺的国内外现状和加工原理,建立了切削滑块槽飞刀的数学模型,设计了加工齿套滑块槽部位的刀具。经过强度和刚度分析,证明刚度问题为首要校核目标。通过优化设计得到基于等刚度原理的飞刀结构,实践检验证明该刀具是适用的。

The gear sleeve of automotive synchronizer is difficult to process.In this paper,the processing technologies of gear sleeve in the world were introduced as wel as the machining principle.The gear sleeve flying cutter cutting mathematical model was established.By means of strength and stiffness analysis,the stiffness is the most important checking target.Special con-stant stiffness cutting tool of the gear sleeve was designed for numerical control machine,and it is proved that the cutting tool is suitable for cutting.
