The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

本文主要是以DEFORMTM有限元素软体模拟U型钢片连续道次成型与单一道次成型以确认单一道次模拟的是否可取代连续道次模拟之研究。因DEFORMTM 软体对於网格元素上的限制故使用较短素材120mm通过所有的成型站以模拟工厂实际连续成形方法。辊轮间隙固定为0 3mm；辊轮转速为20 rad/sec；弯曲角度的方法为将成型角度平均除以成型站数。有三种辊轮成型方式被选择分别为6站，9站，与12站。在模拟的过程中有两种现象会产生 Case A，素材通过单一成型站。Case B，素材会通过两个成型站。因为在模拟过程中素材的两端会有拉应力与扭力。Case B的模拟比Case A像实际的制程，并计算应力与应变在U型断面的Tip部中可发现Case A比Case B低约15%。从Case B的每站的结果可以得知，12站的成型应力最小，9站次之，6站最后。

A new study idea that makes the occupant injury prevention research and CAD/CAE technology on an integrate mathematical model by means of feature theories and feature design technologies was brought, and it is maybe useful if we study automobile passive safety on a new view of point.The conclusions of this thesis included that what are the main factors of airbag-related injuries and the preventive measures, based on the research of the relationships between injury parameters, such as HIC, chest acceleration, neck force, neck moment, femur axial force etc, and impact speed, belt-use, occupant size (50th and 5th), sitting position and so on. The thesis evaluated whether the effectiveness of the airbag can be increased by making the airbag adaptive to the crash conditions, and points out that the size of the ventilation hole has the dominating influence on the performance of the airbag and is a key factor for intelligent airbag, multi-stage and lower-power inflator can cost effectively minimize the risk of injury to occupants from crashes. It is important for the researchers of intelligent airbag to keep the small size unbelted occupants in focus and it is necessary to study deeply the influence of airbag fold patterns and the extremity out-of-position situation. These topics are important in the study of occupant injury prevention and vehicle safety design.
