Cross-sectional distortion behaviors of thin-walled rectangular tube in rotary-draw bending process ZHAO Gang-yao(赵刚要), LIU Yu-li(刘郁丽), YANG He(杨 合), LU Cai-hong(卢彩红) College... distortion usually appears during rotary-draw bending process of thin-walled rectangular tube with small bending radius. To study the cross-sectional distortion of the tube, a three-dimensional finite......
Sensor array calibration for uniform rectangular array in presence of mutual coupling and sensor gain-and-phase errorsWANG Ding(王鼎), YAO Hui(姚晖), WU Ying(吴瑛) (Institute of Information System Engineering, PLA Information Engineering University, Zhengzhou 450002, China)Abstract:The sensor array calibration methods tailored to uniform rectangular array (URA) in the presence of mutual coupling......
casting and the hot-rolling process. The mechanical properties, conical cup value (CCV), bore expanding performance, and limit drawing ratio (LDR) were investigated to examine the stamping formability of ZE10 alloy sheets, at temperatures ranging from 20 to 300 ℃. The results showed that the tensile strength decreased, whereas, plasticity, drawing-bulging performance, bore expanding properties, and deep......
