起皱的

He unbuttoned successively in reversed direction waistcoat, trousers, shirt and vest along the medial line of irregular incrispated black hairs extending in triangular convergence from the pelvic basin over the circumference of the abdomen and umbilicular fossicle along the medial line of nodes to the intersection of the sixth pectoral vertebrae, thence produced both ways at right angles and terminating in circles described about two equidistant points, right and left, on the summits of the mammary prominences.

他那双手的轨迹从参差不齐、卷缩起皱的黑色体毛的中心线——也就是自骨盆底到下腹部肚脐眼周围那一簇簇体毛，又沿着节结的中心线进而延伸到第六胸脊椎的交叉点，从这里又向两侧丛生，构成直角形，在左右等距离的两个点，即环绕乳头顶端形成的三角形收敛图形的中心线——穿行。

In order to compare the results for the three different die gaps, the ratio of the two principal strains is introduced, being min/max, where max and min are the major and the minor principal strains, respectively. Hosford and Caddell [5] have shown that if the absolute value of is greater than a critical value, wrinkling is supposed to occur, and the larger the absolute value of , the greater is the possibility of wrinkling.

为了比较三种不同模具间隙的结果，两种主要张力的比率被介绍-是最小值/最大值，这里最小值/最大值是主要的和次要的张力，分别的， Hosford and Caddell [5] 显示如果他的绝对值比临界值大，起皱应该会产生，越大的绝对值，则越大的起皱产生。

There are three types of wrinkle which frequently occur in the sheet metal forming process: flange wrinkling, wall wrinkling, and elastic buckling of the undeformed area owing to residual elastic compressive stresses.

在金属板料成型加工中通常存在三种类型的起皱现象：法兰起皱，侧壁起皱，和由于残余压应力在未变形区产生的弹性变形。

I find that very depressing, especially when the same customer then picks up one of my knives, hefts it, frowns, puts it down and walks on.

我很郁闷，特别是当同一个顾客拿起我的刀，掂了掂，皱皱眉头，放下，走人。

Based on Hill' elastic-plastic instability theory,the velocity field for sheet instability which is caused by the shear stress during sheet metal forming is developed,and the theoretical formula of the wrinkling critical shear stress is proposed.

以Hill关于弹塑性失稳理论为基础，建立了剪应力起皱失稳的速度场分布，给出了临界起皱剪应力理论计算结果，分析了板料屈服强度、硬化指数、板厚方向性指数及板料厚度对临界剪应力的影响，并与实验和数值模拟结果进行了对比。

The simple structure of the scraper, to facilitate adjustment by promoting the scraper plane rotating cylinder, pressure gasbag promote post-marked pressure on the blade of the complex, to make up for the automatic dryer cylinder as a result of uneven surface without wrinkling or uneven wrinkle defects Applicable to a wide range of high low-speed paper machine.

该刮刀结构简单，调整方便，通过气缸推动刮刀架转动，气囊推动后压标对刀片加压的复合运动，能自动弥补因烘缸缸面不平而不起皱或起皱不均匀的缺陷，广泛适用于高低速纸机。

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。
