Stretch Forming Process of Rail Vehicle Body End Beams
During the stretch forming of end beam components, common defects include web buckling and sidewall cross-sectional distortion. The severity of cross-sectional distortion increases with the amount of stretch. For this component, a reasonable stretch amount is 8% of the profile length, and the corresponding mold surface correction should be set to 1.3 times the springback. […]
