In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.

此外，本文还研究了圆锥形件拉深成形过程中，随着拉深变形过程的进行，毛坯为避免产生起皱、破坏缺陷而对压边力的需求情况，阐明了圆锥形件拉深成形过程中压边力合理变化的必要性；由毛坯主要变形区悬空锥壁部分的受力变形情况，从力学分析的角度，首次推导得出了圆锥形零件悬空锥壁起皱失稳的临界条件；并根据主要变形区法兰、悬空锥壁及凸模圆角部分的塑性失稳临界条件，在其成形范围图中，将圆锥形件成形过程中的压边力划分为四个区域；总结并提出了圆锥形件成形过程中压边力合理变化的基本原则；建立了防止起皱、破坏缺陷产生的压边力合理变化的数学模式，并得到了有限元数值模拟及网格实验法的验证，证实了理论分析结果的正确性和可靠性。

If the blank is wrinkling on the blank holder surface, the cause is most likely one of four factors: insufficient blank holder force; a poor fit between the die face and blank holder surface; an equalizer block that is holding the die face apart from the blank holder surface; or severe blank holder deflection.

如果板料在压边面上起皱，绝大多数起因是后面四个因素之一：不充分的压边力；凹模和压边圈表面不良的匹配；凹模和压边圈间的平衡块；或者是压边圈的严重变形。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸比直接体现在拉延凸模和板料边缘之间的关系--拉延凸模和板料边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和凹模表面间有额外金属板表面被夹紧。

I am a wilful child perhaps My mother was spoiled child I wayward I hope Every moment As beautiful as crayons I hope The white paper in love can draw Draw clumsy freedom Draw a never Tears in eyes Sky A sky plumage and leaves A green night and apples I want to paint in the morning Under the picture Can see the smile Under the picture all the young No pain of love She hadn't seen clouds Her eyes are clear color She looked at me forever Forever, watching Never suddenly fell away I want to paint distant scenery Under the picture of the horizon and the water is clear Painted many happy river Under the picture Lightly covered with fluff I let them get very close Let them fall in love Let each one Each a silent spring throb Have become a little birthday I also want to paint in the future I haven't seen her, it is impossible But know that she is very beautiful I painted her coat of autumn Under the burning candle painting and maple leaf Painted many because love her And out of the heart Under the picture Draw a woke up early The glass wrappers above And the fairy tales illustrations I am a wilful child I want to wipe away all the unfortunate I think in the earth Painted with Windows Let all habits dark eyes All light I want to paint surface Draw a frame under a higher than the mountains Draw down the Orient Under the picture A voice of limitless Finally, in the paper Angle I also want to paint Draw a koala He sat on the dark jungle in Victoria Sit quietly branches Become speechless He had no home No one in the distance He only, many The same dream. Berries And a big, big eyes I hope think But I wonder why I didn't receive crayons Don't get a color moment I only have me My fingers and trauma Only the pieces Love her Let them go looking for a butterfly Let them vanish from today I was a child A mother is spoiled child fantasies I wayward

我是一个任性的孩子也许我是被妈妈宠坏的孩子我任性我希望每一个时刻都像彩色蜡笔那样美丽我希望能在心爱的白纸上画画画出笨拙的自由画下一只永远不会流泪的眼睛一片天空一片属于天空的羽毛和树叶一个淡绿的夜晚和苹果我想画下早晨画下露水所能看见的微笑画下所有最年轻的没有痛苦的爱情她没有见过阴云她的眼睛是晴空的颜色她永远看着我永远，看着绝不会忽然掉过头去我想画下遥远的风景画下清晰的地平线和水波画下许许多多快乐的小河画下丘陵长满淡淡的绒毛我让它们挨得很近让它们相爱让每一个默许每一阵静静的春天悸动都成为一朵小花的生日我还想画下未来我没见过她，也不可能但知道她很美我画下她秋天的风衣画下那些燃烧的烛火和枫叶画下许多因为爱她而熄灭的心画下婚礼画下一个个早早醒来的节日上面贴着玻璃糖纸和北方童话的插图我是一个任性的孩子我想擦去一切不幸我想在大地上画满窗子让所有习惯黑暗的眼睛都习惯光明我想画下风画下一架比一架更高大的山岭画下来东方民族的渴望画下大海无边无际愉快的声音最后，在纸角上我还想画下自己画下一只树熊他坐在维多利亚深色的丛林里坐在安安静静的树枝上发愣他没有家没有一颗留在远处的心他只有，许许多多浆果一样的梦和很大很大的眼睛我在希望在想但不知为什么我没有领到蜡笔没有得到一个彩色的时刻我只有我我的手指和创痛只有撕碎那一张张心爱的白纸让它们去寻找蝴蝶让它们从今天消失我是一个孩子一个被幻想妈妈宠坏的孩子我任性

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.
