A NSYS 在大型盘铣刀结构设计中的应用 宋丽鸽, 张志军, 宋建超, 郑站强 ( 沈阳理工大学 机械工程学院, 辽宁 沈阳 110159) : 曲轴是船用发动机的关键部件在加工过程中常因为振动而严重影响到其加工质 为了 减小大型盘铣刀在机加工时的振动, 提出了在刀盘上安装冲击减振器的设计方案, 但减振器的最佳安装 位置有待于确定本文正是通过对在改变刀盘上所开圆孔的半径r 和距离d (盘铣刀中心到孔中心) 条件 下盘铣刀的强度分析, 总结出参数r 和d 对应力应变 的影响规律, 为预知所要安装冲击减振器的最佳 半径和位置提供了依据, 也为盘铣刀的结构设计提供了一种方法 : ANSYS; 大型盘铣刀; 强度分析; 结构设计 : T G 7 14 : A The Application of ANSYS on Structural Design of Large Discmill Cuter SONG Lige, ZH A NG Zhijun, SONG Jiancha , ZH ENG Zhanqiang ( Sch l f Mechanical Engineering , Sheny ang University f T echn l gy, Shenyang 110159, China) Abstract: Crankshaft is t he heart f marine engine, but it alw ays pr duces much vibrat i n during the pr cess , w hich se ri usly affect the qualit y f the crankshaft. T reduce the vibrati n during machining f the large discmill cuter, the scheme f installing impact dampers in large discm ill cuter is pr p sed. But the best installing l cati n f impact dam pers need de terminati n. This paper analyzes t he strength f large discmill cuter based n finite element meth d, t hr ugh the analy sis f st rain and stress by changing f h les radius r and d( the distance between the center f h le and large discmill cuter) , the law f paramet ers r and d influence n stress and st rain is Summarized. T his w ill pr vide a basis f r the best radius and p si t i n f im pact damper , als pr vide a w ay f structural design f r discm ill cuter .
