| 1 | Light weight replacement and the optimization design of bumper beam based on crash safety显示文摘Bumper beam is one of the key structural parts,which plays an important role in the frontal crashes of automobile.With the global trend of light-weighted automotive parts,the light weight of bumper beam attracts extensive attention of automobile manufacturers,and hot stamping technology with significant weight advantage has become one of the main light weight measures for bumper beam.The quasi-static press,low speed crash and frontal crash simulation models of bumper beam were established according to its actual working conditions in the automobile crashes.The feasibility of replacing normal steel bumper beam with hot stamping bumper beam was analyzed.Meanwhile,the stiffeners in the front face of hot stamping bumper beam were optimized with topography optimization in order to further improve its performances. | Zhang Jingwen | 2014 | Engineering Sciences2014，12，5： | 1 |
| 2 | Finite Element Analysis of Stamping of Automobile Beam显示文摘With the development of numerical simulation and analysis technology, plastic forming theory, stamping technology and computer technology, DynaForm technology with a finite element as the core has been developed rapidly. DynaForm technology for sheet metal stamping can simulate the entire process of sheet metal stamping. In this paper, the metal beam is used as the research object, and the fi nite element analysis is carried out by DynaForm software. The causes and control methods of the typical defects in the forming process are analyzed. The radius, punching speed, Coeffi cient, blank holder force, drawbead and other parameters on the quality of the impact of automotive beams. Combined with the actual production of a reasonable forming process and improve the way. The simulation used to guide the practice, can shorten the mold development time, reduce the cost of molds, improve business income;the production practice has a certain guiding signifi cance. | Xiaoli Fu Yuedong Qiu Mingtu Zhao | 2018 | Computer Simulation in Application2018，1，1： | 1 |
| 3 | Simulation about hot stamping of ultra-high strength steel on the basis of lightweight technology显示文摘With the development of automobile lightweight,it is very necessary to apply the ultra-high strength steel parts manufactured by hot stamping,which offers the possibility to reduce the weight of automobiles and maintain the safety requirement.In order to complete hot stamping,it is important to design the structure of parts reasonably,which is related with reasonable matching of strength.The objective of this paper is to guide the design of parts manufactured by hot stamping and find the forming technical requirements of vehicle performance.Through experiments,the paper obtains the stress and strain curves at different deformation temperatures and strain rates.Based on experimental data, the constitutive relationship model is established which can reflect the deformation capacity of ultra-high strength steel during the process of hot stamping.Combined with finite element simulation results of hot stamping by commercial software AUTOFORM,transfer path of load and matching law of strength,the paper determines the design criteria and forming technical requirements of parts manufactured by hot stamping.At the same time,the impact performance of front cross member internal plate is taken into consideration. | Liu Qiang Ma Fangwu Wang Xiaona Yao Zaiqi Song Wei Zhao Fuquan Ma Mingtu Song Leifeng | 2012 | Engineering Sciences2012，10，6： | 0 |
