In order to systematically investigate the inner wall bending stress of the rolling element in elastic composite cylindrical roller bearing, finite element analysis......
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......
A new adaptive bending method using closed loop feedback control T. WELO, B. GRANLY Department of Engineering Design and Materials, Norwegian University of Science and Technology (NTNU), Richard... improving product quality is required. A new rotary compression bending set-up with automated closed-loop feedback control is thus being developed. By transferring in-process measurement data......

A Mechanical Model for Three-phase Permanent Deformation of Asphalt Mixture under Repeated Load赵永利School of Transportation,Southeast University摘 要:On basis of the Burgers model, a new model consisting of modified dashpot and Van Der Poel model was derived from rheological and viscoelastic theory. Subsequently, triaxial repeated load permanent......
. The equivalent load method was employed to account for random repeated loads in structural reliability analysis. Degradation of material strength was regarded as a Gamma process. The probabilistic... degradation and repeated load is closer to the practicality than the method of considering reliability calculation only. Its decreasing velocity is faster than the traditional reliability. The reliability......
