【摘要】 低压电器开关柜产品的个性化设计既是当前市场的实际需求,也是其发展的必然趋势。由于缺乏系统的理论和专门的定制化设计工具、电器元件的标准化工作不理想、二次控制系统复杂多变等一系列原因,导致低压电器开关柜面向客户需求的定制化设计和生产组织管理水平普遍不高,产品的设计及制造质量不够稳定,因此,研究低压电器开关柜定制设计技术具有较好的学术和工程应用意义。在系统地分析低压电器开关柜产品的结构和设计特点基础上,根据企业在产品设计过程中反映出的实际问题,提出了一种模块化、可视化的低压电器开关柜设计方法,规划了面向客户定制的低压电器开关柜CAD系统的总体功能,并且对该系统的功能单元建模、可视化排布、开孔图的自动生成、物料自动统计等关键技术和方法进行了研究,具体内容如下:①以独立功能单元为基础,研究低压电器开关柜的模块化设计方法。以可视化的功能单元排布、物料自动统计和面板开孔图自动生成为目标,重点对功能单元的数据结构进行了分析研究;②研究低压电器开关柜的功能单元可视化排布方法。提出了解决可视化排布的基本思路,并对其中的有关图形处理和人机交互技术进行了研究;③研究面板开孔图的自动生成技术。提出了由功能单元排布信息导出开孔信息,由开孔信息自动驱动面板零件三维模型实现开孔,由三维模型自动生成二维工程图的面板开孔图自动生成方法;④研究低压电器开关柜产品设计的物料自动统计方法。提出了基于模块组合的物料信息自动统计思路,并对其中的物料分类统计与报表生成等关键问题实现进行了研究。⑤基于VB6.0语言、Access数据库和Solidworks三维设计软件,开发出了一套低压电器开关柜辅助设计系统,该系统可以较好地实现所规划的全部功能。本论文的研究成果已在企业得到了初步应用。使用所开发的“低压电器开关柜辅助设计系统”,能大大缩短产品设计周期,减少人为出错,提高产品设计的正确率。其中,在物料统计以及面板开孔图生成方面的表现设计人员尤为满意。更多还原

【Abstract】 The design of low-voltage switchgear product design is trending customized, since current market physical demand, is also its development. But the general level of organization and management is not high, product design and manufacturing quality of instability,due to the lack of systematic theoretical and specialized custom design tools,the standardization of electrical components was less than desirable, the second control system Complex and changeable. Therefore,the research of customized design of low-voltage switchgear product has good academic and application significance.In this paper, systematic analysis of the structure and design features of low-voltage electrical switchgear products. According to the actual problem of product design in companies, put forward methods of modular and visual design of low-voltage electrical switchgear, planning the function for the customization of the low-voltage switchgear electrical CAD system. On this basis, the functional unit modeling, visualization arrangement, the automatic generation of opening drawing, materials automatic statistical techniques and methods have been studied as follows:①Based on independent functional units, to study the low-voltage switchgear electrical methods of modular design. This Studying focus on the data structure of the functional unit to achieve visual layout of the functional unit. The material statistics and the panel opening drawing produce automatically.②Research on the methods of visualization of functional unit layout of low-voltage electrical switchgear. Proposed the solution visualization distribution basic mentality, and the related graphics processing technology and human-computer interaction was studied.③Research the automatic production technology of panel opening drawing. Proposed the method of the panel opening drawing produce automatically. First of all, the information derived from the opening arrangement information. Then making the holes of three-dimensional model of panel parts, by information-driven of holes. Finally, making two-dimensional drawings from three-dimensional model automatically.④Research material automatic statistical method of low-voltage electrical switchgear design. Proposed the idea of automatic statistical information materials based on the module combines, and researched the key issues such as Material classification statistics and report generation. ⑤Based on the VB6.0, the Access database and the Solidworks three dimensional design software, developed a set of low-voltage electrical switchgear aided design system, this system might realize the complete function which the present paper planned.Present paper’s research results obtained the preliminary application in the enterprise. By using“the low-voltage electrical switchgear aided design system”, the product design time shorten greatly, human error reduced, and the accuracy of product design improved. Among them, the function of statistical material and opening hole drawing are particularly satisfied with the designers.更多还原
