| With the development of society , technology ,and the increasing of products quality,the value of shape control in metal rolling is getting to take seriously.The key step to realize the shape control is to achieve shape measuring on line.This project of our study is to develop the precise Pneumatic Shapemeter for shape measuring in production of aluminium foil and copper foil,which is still an unknown field in China.There are five sections in this thesis.In each part,I presented separately the some studies on precise Pneumatic Shapemeter,working in Yanshan Uinversity post doctoral program.In Part One,It is introduced the background and situation about this project,the importance of its studying.lt is also introduced the concept of shape,defect type of shape and expression method of shape.And it is briefly introduced factors effecting shape.Through the part,one will known something basicly about the projuct.In Part Two, it is first induced the common requirement of shape measure instruments in the pracical production,summaried the classify of the shape measure instrument according to its working principle.Then carefully introduced the practical usages,working principles,equipment charactristics,and its advangtages and disadvangtages of different shape measure equipments. The introductions above will be good value for further devoloping and researching different types of shapemeters.In Part Three, it is firstly involved the elementary structure,working principle of Pneumatic Shapemeter,analysed its advangtages and disadvangtages according to its using ,maintaining and manufacturing.Then ,put forward the whole design method of Pneumatic Shapemeter,lay a fundation for the design of whole Shapemeter.lt is also involed commonly the need of lift and fall mechanism of the shapemeter , the handling of shape sigal and common shape singal identification in metal rolling.In Part Four,It is dissussed about the main air film and nozzle of Pneumatic shapemeters by making use of numerical method,and getting it combined with whole design of the shapemeter.Firstly, the elementary control equations of air which determines its working of air film and nozzle is intrduced .Through the comparation of common numerical calculating fluid field method ,fixed the adopting method of numerical diffierence ,gave a good reason for choosing this method which calculate this fluid field.Through determining the original and boundary value and dissociation of the field,got a good calculating result.Combining this fluid field calculation, put forword adesigning method connected with the whole design and fixing main film and nozzle of Pneumatic Shapemeter.In order to make the design method more practical and more "friendly",successfully developed auxiliary analysis and design software of Pneumatic Shapemeter by using visual language VC++.And having used this software designed an one-piece and a three-piece samples of Pneumatic Shapemeter and achieve satisfied result. This software is a reliable and helpful for further design and analysis of Pneumatic Shapemeter.In Five Part,in order to examine the design method that put forward in this paper, study its manufacturing ,and know its characteristics of Pneumatic Shapemeter,after firstly designed and manufactured the experiment equipment and Pneumatic Shapemeter sample, the experiments of Pneumatic Shapemeter have been made first in China .In this part,its experiment equipment and sample,the experiment method are related.Then these data got in the experiment are intrduced ,some result of Pneumatic Shapemeter are given according to the experiment.Through the experiment,the conculusion are achieved that the design method which put forward in this paper is valuable,the manufacturing method is reasonable,and the design requirment of Pneumatic Shapemeter sample are met.Three main parts are introduced through five chapters of this paper.It is introduced the background and some concerned concept of this project,and the present resarch of shapemeters all over the world.It is in...
