The study on the experiment of wall thickness deformation of coreless bended small-diameter tube 小直径管无芯弯曲壁厚变形的试验研究
Bauschinger effect of bended plates and influence of manufacturing technology on yield strength of tube body 弯曲板中的包申格效应及制管工艺对管体屈服强度的影响
Familiar defects of bended tube and solving methods 常见弯管缺陷及措施
I analyzed present researches of the shaping quality of NC tube bending from home and abroad, and based on these analyses, I analyzed the working condition of the tube when being bended and established the theoretical mechanics model of NC tube bending. 在对国内外学者对数控弯管成形质量研究现状的分析基础上,分析弯管受力情况,建立数控弯管理论力学模型。
