ABSTRACT Title of Theme: Numerical Simulation and Controlling of Dimples on the Process of Multi-Point Forming for Sheet Metal Specialty: Material Processing Engineering Faculty Adviser: Prof. Cai Zhongyi Multi-point forming is a new means for sheet metal forming.

论文题目：板材多点成形中压痕的数值模拟及控制专业：材料加工工程指导老师：蔡中义教授多点成形（Multi-point forming，简称MPF）是一种全新的板材成形方式。

Incorporated with the state-of-art technology developed by the famous application manufacturers in China and abroad, our technology has been extensively applied to all types of plane plates and allotype materials.

结合国内外著名涂装厂商研发出的新型工艺已广泛应用于各种平面板材及各种异型材料，例如：家具板材、橱柜板、地板、百叶窗、发泡板、梯脚板、礼品盒、金属板、石材板等。

Aluminous car is to use 6061 alloy profile and 5083 alloy plank or 6061 alloy plank to make.

铝车辆是用6061合金型材和5083合金板材或6061合金板材制造。

In MPF, the dynamic explicit finite element arithmetic is very suited to simulate the sheet metal forming because the contact between the elements and the sheet is discontinuous and the loading condition is very complicated.

在板材的多点成形过程中，由于基本体和板材之间接触状态不断发生变化，加载条件及其复杂，应用动态显式有限元算法求解具有明显的优势。

Water not easy to vaporize under the slab, and will continue to basification function with cement, cause the erode and curve even break

水份在板材下面难以蒸发，继续与水泥发生碱化作用，导致板材受侵蚀以致翘角甚至爆裂。

This article thesis is aimed at exploring the overall structure design of plate edge milling machine, that is the design of plank stuff edge milling machine, also called the design of board groove machine.

摘要本文旨在探索板材坡口机的总体结构设计，即板材坡口机的设计，又称板材坡口机设计。

Furniture is to use a European E1 environmental green plate surface texture clear and not plank reflective reflex the light is downy not easily fatigue to protect your eyes, ps, thick interlocked characterization, high temperature resistant, light, not because of violence to waste their and shrinking or excessive temperature, after sealing side seam appearance, minimum makes glue, good performance to prevent dust into the colleague and obtain the biggest humidity-proof property.

我们公司的家具是采用欧盟E1级环保绿色板材板材表面纹理清晰而且不反光反射光线柔和不容易疲劳有利于保护眼睛板面厚，不易透底，防刻划，耐高温，强光暴嗮，板材封边带是采用德国瑞好封边带不会因为温差而出现过度收缩或膨胀，封边后使得胶缝最小，外观性能好，防止灰尘进入的同事防潮性能也得到最大的满足。

The evolvement of grain orientation for the sheets during this processing and the influence of channel clearance on it were investigated.The results indicate that the shear stress and compression stress are put on the sheet at the channel corner during equal channel angular rolling.And the shearing deformation on...

结果表明，在等径角轧制过程中，板材在模具转角处受到剪应力和压应力的作用；随通道间隙的增加，板材的变形由剪切变形演变为剪切+弯曲变形，甚至弯曲变形；由于剪应力的作用，AZ31镁合金板材的晶粒取向由普通轧制所形成的基面取向转变为等径角轧制后的非基面取向，随着剪切变形量的减小，基面沿轧制方向的偏转角度也逐渐减小。
