The results show that upper bainite of 9Cr2Mo Steel and GCr15 steel is feathery and the upper bainite carbide is lamellar or claviform. The upper bainite carbide distributes between the subunits of bainite ferrites by and large parallelly to the axis of bainite ferrites. Lower bainite of 9Cr2Mo Steel and GCr15 steel is in bamboo leaf shape and the lower bainite carbide is in shred or fibre shape. The lower bainite carbide distributes between the bainite ferrites, furthermore, the angles between lower bainite carbonide and the principal axis of the lower bainite ferrites are unequal.

结果表明,9Cr2Mo钢和GCr15钢的上贝氏体组织呈羽毛状,上贝氏体碳化物呈长短不一的薄片状或短棒状,分布在铁素体亚片条或亚单元之间,其排列与贝氏体铁素体片条轴向大体上平行分布;下贝氏体组织呈竹叶状或针状,下贝氏体碳化物呈细片状或纤维状等形状,分布在铁素体片中间,大多数与片条的主轴方向交角排列,但角度不等。

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。

Finally, the parameters, such as density, thickness of porous media, thickness of steel of each material in air and porosity, pore size, thickness of porous materials, thickness of steel and incident angles in water were investigated and also the influence on the sound absorption and insulation were discussed.

最后,分别就空气中以及水中的材料参数,分门别类的观察其对吸音与隔音的影响。在空气中所讨论的参数,有多孔材密度、多孔材厚度、钢材厚度。在水中所讨论的参数,有多孔材孔隙率、孔隙尺寸、多孔材厚度、钢材厚度、声波入射角度。
