PREDICTION AND OPTIMIZATION ANALYSIS OF DURABILITY PERFORMANCE OF AUTOMOTIVE CLOSURES by GUO PengBo, LIU Zhe, LI Hui, GAO DaWei

“…Aiming at the fatigue failure problem of a car door opening and closing process.The Hypermesh was used to construct a finite element model of door opening and closing,and then Ls⁃Dyna,an explicit dynamics solver,was used to establish a nonlinear transient dynamics model of door opening and closing.The d3plot file containing the stress⁃time history solved by the nonlinear transient analysis was imported into nCode DesignLife to build the fatigue analysis module,and the results were verified with 100000 times of door opening and closing durability tests,and the conclusions show that both of them have good consistency in terms of the damage location and the damage degree.Finally,multi⁃particle swarm optimization(MPSO)was used to optimize the door with the objectives of door lightweight and minimum damage,and the optimal solution was selected according to the engineering reality,which reduced the mass of the door assembly by 0.17 kg,and the damage value of the door was reduced by about 24.33%.The optimization results show that the MPSO algorithm can be effectively applied to the multi⁃objective optimization design of the door,which provides certain ideas for the design and development of the subsequent door.…”

Analysis of Deformation Characteristics of Dikes on Deep Soft Soil Foundations by WU Juan, ZHANG Ming, LI Yansong, HOU Weijian

“…The deformation of dikes directly affects the safety of dikes,especially for dikes on deep soft soil foundations,whose deformation is often large,and thus it is often used as the main evaluation index of dike safety.By the reconstruction project of a dike on soft soil foundations,the finite element numerical analysis model for the typical section of the dike is built,and the deformation of the dike during the completion period and under the characteristic water levels is calculated,with emphasis on analyzing the influence of the water level changes and pressure platform on the deformation characteristics of the dike.The results indicate that the dike settlement is severe,and the severe settlement area is mainly concentrated near the center of the surface layer of the dike foundation,and the soft foundation has a significant impact on the dike settlement.The horizontal deformation is relatively small,mainly concentrated in soft foundations,and the horizontal deformation of the dike body is slight.The pressure platform on the waterside slope and the water level changes near a river have a great influence on the horizontal deformation of the dike.On the whole,the dike design scheme is reasonable,and it is suggested to reserve a sufficient settlement amount at the top of the dike.…”
