Study and analysis on the defects of bus skin based on strain distribution

LI Xiao-gang;LIU Li-xian;LI Chun-guang;CHEN Qing;ZHAO Ning;YANG Jian-wei;ZHAO Ai-min;Engineering Research Institute,University of Science and Technology Beijing;Application Technology Department,Research Institute of Technology;  
In the roll forming process of the bus skin,some bag-shaped wave and edge wave were produced on the central portion and the edge due to the strain was uneven distribution,and the causes and mechanism of defects covering skin were systematically analyzed.To solve the bag-shaped wave and edge wave,some technical measures were proposed such as appropriate adjustments to the rack from the pitch,roll gap and forming the bottom line clearance etc.to give a good effect.
