【摘要】 自古以来，面料的性能完全凭借经验进行设计。面对企业的技术现实和快节奏高品质的市场需求，研究生何雪莲采用课题组的多项研究成果尝试开发了精纺毛型面料服用性能预测软件初级版(WFCAD1.0版)，把一些实用但繁琐的设计与计算工作交给计算机完成，取得了比较好的试用效果，使纺织行业的产品性能设计由目前的经验型方法上升到快速的智能设计水平。但由于研制时间仓促等原因，原有软件还存在许多不足，与实际生产的要求还有一定的距离。推广应用面料性能的智能设计软件，一方面需改进已有的功能，另一方面要增设一些新的功能，例如增加设计预测化纤面料功能。本论文在前人的理论与实践研究基础上，研制开发了功能更加完善的面料性能设计软件。 收集、分析、整理用户意见等有关资料并对原有软件进行详细分析和研究后发现，对原有软件的改进性维护已经不能解决实际问题，总体上重新开发软件、延用已有软件的个别功能模块是比较合理的开发路线。考虑新开发的软件中所需经纬纱线的种类和每种纱线所用原料的数量增多，并且要求既能设计单纱、股线还能设计更加复杂的纱线等，在编制程序时主要采取了以下几方面技术措施： (1)面料设计部分主要考虑将面料设计的整体放置在一个窗体上，使用TabStrip控件将面料设计参数分为三组(原料设计、纱线设计和织物设计)分别放置在三个Tab选项中，点击选项界面上的某些设计命令按钮，相应地出现原料设计窗体、纱线设计窗体。这样，改变了原有程序的面料设计窗体多、层次不清晰等弊端，又利于增加Access类型数据库，并将屏幕的全部信息保存在数据库中。通过数据控件与数据表各对应字段相连接，使窗体数据与数据库对应表中的数据同步变更，或采用将数据库表中特定的记录数据读到数组中，再将数组中的值赋给该窗体中相应的数据控件，从而将数据库已有(或刚设计)的面料参数调出返回到面料设计的有关界面，能够稍加修改就可完成新的面料设计，改变了原有程序没有保留设计参数，而不能实东华大学硕士论文摘要现修改功能给应用中带来的不便。 (2)预测计算部分与原有软件相比，内容更全面，操作方便可靠，布局也更美观、更合理。如力学量窗体能根据操作要求的不同，部分按钮有时显示为灰色，有效地防止了错误操作，并根据设计面料的类型选用相应的预测计算公式。 (3)汇总输出部分，重新布置了汇总单窗体上的内容，并设法使打印出的汇总单上内容合理地分布在A4纸上，避免原有程序的数据太拥挤，纸张利用不合理及汇总不全面。 (4)增设的工具模块、成形性专家系统模块以及更加详细的帮助模块等协助设计人员更好地使用此软件。 (5)在数据库的规划方面，根据数据库中数据之间的关系，把数据分成同类的逻辑单元，建立一对多、一对一类型的关系数据库，如原料设计时，将类似的数据分别以不同的记录进行保存即每一种原料设计信息保存一条记录，从而大大节省了数据库的储存空间。 (6)在编程时使用大量的控件数组以及变量数组，并将数组元素的下标和循环语句结合使用以及将控件数组与变量(或变量数组)联系起来，使程序代码的编写简洁而高效，结构清晰、容易理解和方便维护等。 本软件是根据企业的具体需求而开发的，在设计上以实用为主。主要实现快速地进行精纺毛型面料和化纤面料的设计、预测其性能，并能对面料数据库进行维护管理，实现添加、修改、删除、查找、保存、打印等功能。由于其预测效果比较准确，因而对生产实践有一定的实用价值，成为参与市场竞争的重要技术手段。相信随着计算机的普及，面料性能预测及设计软件在面料生产行业中的应用也必然成为潮流和趋势。更多还原

【Abstract】 The fact that fabrics’ performances are designed in term of experience is not changed until now. In order to meet the technical reality of mills and market demand for textile with high quality, an original software (WFCAD1.0) had been programmed by Xuelian He, a graduate. This software achieved good effect in practice for two reasons. One was that a lot of useful but complicated designs could trust with computer, another was fabrics’ performances could be designed according to the parameters of fabrics instead of depending on people’s experience. However, this software can’t agree with some requirement of practice. To make this software used widely, two things have been done: firstly, some existed functions were revised; secondly, some new functions such as design of filament fabric were added. This paper will emphasize on a software perfecting the functions of fabrics’ performance designing on the basis of the achievement of theory and practice.Advises coming from the customers to the original software and our analyzing to the software suggested that only maintaining the existed software couldn’t solve the practice’s problems. It’s more available to develop a new software using only one or two modules of the existed. Considered more kinds of materials applied and yarn designing included not only single-yarn and compound yarn but also more complicated yarns, several technical measures were adopted as following.(1) As for fabric designing, it was considered as a whole in one window. The designing parameters divided into three groups (raw material designing, yarn designing and fabric designing) by TabStrip were set as three Tab options. Then the needed windows such as material designing, yarn designing will be presented with clicking the buttons. What has been done not only overcomes those shortcomings such as toomany windows, layers’ disorder, but also is helpful to add the database of Access and save all the designed information into the database. The data existed in the database or designed can be used in the related designing windows by two ways. One is that the data in windows is changed responding to the change of database linked by data control and corresponding fields. Another way is that the data in the database is recorded to arrays, and then arrays are referred to the corresponding data control. Then the software can meet the designing demand with a little revision, and overcome the inconvenience brought by the existed software that can’t save designed parameters.(2) As for the part of prediction and calculation, compared with the existed software, the advantages of this software are obvious: contents more comprehensive, operation more convenient and layout more reasonable. For instance, some buttons show gray in some cases in term of the requirement so that improper operations are avoided, and the needed predictive equations are selected responding to the type of fabric designed.(3) As for the output, the summary was rearranged that makes the printed result showed clearly on the paper with A4 size, and also the content is more comprehensive than before.(4) The software can be easily used with the help of some useful modules such as tool module, expert system on the formability, and the detailed information of the guide.(5) Based on the relation of the data, the same logistic was separated, and then the related database of one to more, one to one was set up. For example, when materials are designed, similar data was respectively saved as a different record. That is, the designing information of every kind of material is taken as one record so that great memory space is saved.(6) During the process of programme, a great number of control arrays and variable arrays are used, together by combining the subscripts of the element of arrays with circle sentences, and connecting control arrays with variable (or variable arrays), which make the programme brief and efficient, make the structure clear, easily understandable and easy to maintain.更多还原
