摘要:
以易拉罐为薄壁圆筒试件,设计并加工了一组局部刚性夹持结构,对局部刚性夹持试件进行外压试验,考察了局部限制约束对薄壁外压圆筒稳定性的影响,同时利用有限元软件ANSYS对结构进行了特征值屈曲分析和几何非线性屈曲分析。试验与有限元计算表明:临时性局部限制约束可以提高外压薄壁筒体的抗失稳能力,并且薄壁圆筒的失稳临界压力和失稳波形数随刚性夹持件宽度的增加而增大。
Abstract:
Cans are taken as thin-walled cylindrical shell specimens subjected to external pressure.A group of local rigid clamping structure is designed and manufactured.An experimental study is carried out to discover the influence of local confined constraint on the stability of thinwall cylinder under uniform external pressure.The eigenvalue buckling analysis and geometric nonlinear buckling analysis are employed with the aid of ANSYS.The experimental and finite element results indicate that temporary local rigid confined constraint can effectively improve the critical pressure of the thinwall cylinder subjected to external pressure.Meanwhile,the critical pressure and buckling wave number of the specimen increase gradually with the increase of clamping width.
