Abstract：Four criteria of forming components by superplastic air bulge have been considered as: ratip of width to depth, W/H, ratio of rotary to bottom angle, r/r_0, distribution of forming material, F/S,and angle difference, θ-φ. An empirical dimensionless expression of combined criterion was proposed to be: Q=((WS)/(HF))+(π/180)(θ-φ)-(r/r_0)+0.55 The left-right crosswise duplex helix components were formed by superplastic air bulge. Their formability was determined by the criterion of typical case Q=l under given conditions. It is believed that the judgement of formability and evaluation of forming operation of components by the above mentioned criterion seem to be available. 收稿日期: 1987-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王春荣 曹淑芝 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I4/363 1 王春荣,高子明,潘学卿,曹淑芝,申淑兰.金属成形工艺,1984;(4) :10 2 王春荣,潘学卿,高子明,曹淑芝,申淑兰.锻压技术,1984;9(4) :4 3 Thomsen T H, Holt D L, Backofen W A.
