1Design of lightweight magnesium car body structure under crash and vibration constraints显示文摘Car body design in view of structural performance and lightweighting is a challenging task due to all the performance targets that must be satisfied such as vehicle safety and ride quality.In this paper,material replacement along with multidisciplinary design optimization strategy is proposed to develop a lightweight car body structure that satisfies the crash and vibration criteria while minimizing weight.Through finite element simulations,full frontal,offset frontal,and side crashes of a full car model are evaluated for peak acceleration,intrusion distance,and the internal energy absorbed by the structural parts.In addition,the first three fundamental natural frequencies are combined with the crash metrics to form the design constraints.The wall thicknesses of twenty-two parts are considered as the design variables.Latin Hypercube Sampling is used to sample the design space,while Radial Basis Function methodology is used to develop surrogate models for the selected crash responses at multiple sites as well as the first three fundamental natural frequencies.A nonlinear surrogate-based optimization problem is formulated for mass minimization under crash and vibration constraints.Using Sequential Quadratic Programming,the design optimization problem is solved with the results verified by finite element simulations.The performance of the optimum design with magnesium parts shows significant weight reduction and better performance compared to the baseline design.Morteza Kiani Imtiaz Gandikota Masoud Rais-Rohani Keiichi Motoyama 2014Journal of Magnesium and Alloys2014,2,2:24

4Esophagotracheal fistula caused by gastroesophageal reflux 9 years after esophagectomy显示文摘Fistula between digestive tract and airway is one of the complications after esophagectomy with lymph node dissection. A case of esophagotracheal fistula secondary to esophagitis 9 years after esophagectomy and gastric pull-up for treatment of esophageal carcinoma is described. It was successfully treated with transposition of a pedicled pectoralis major muscle flap.Kiyotomi Maruyama Satoru Motoyama Manabu Okuyama Yusuke Sato Kaori Hayashi Yoshihiro Minamiya Jun-ichi Ogawa 2007World Journal of Gastroenterology2007,13,5:2
