摘要

以3 层SPF/DB 钛合金空心桁架结构为研究对象，通过平面应变有限元模型，研究了空心结构几何参数对超塑成形过程应力应变分布的影响以及与表面褶皱产生的关系，并进行了试验验证，得到了满足超塑成形工艺要求的参数调控范围，为3 层SPF/DB 空心结构设计提供依据。

Abstract

Influence of geometric parameters on the stress and strain distribution and the occurrence of surface groove during superplasic forming is simulated based on a plane strain model for three-sheet titanium SPF/DB hollow truss structure.Parameter ranges satisfying superplastic forming process requirement are obtained after experimental verification

providing a basic for design of three-sheet SPF/DB hollow structure.
