【摘要】：随着经济发展的全球化、市场竞争的日益激烈,我国的装备制造业面临着巨大的挑战。为了能更好地适应这一国际形势,提高国产机械装备的技术含量,赢得国内外市场,本文以CXT系列电动葫芦为载体,研究其模块化设计的方法,结合前人的研究成果,提出了自己的一套模块化设计体系。模块化思想在装备制造业中前景广阔,未来必将会得到大力的推广。模块化设计方法作为一种新的现代设计方法和思想,在对事物的构成模式分析、机构优化和系统的分解、重组、协调等方面,有其独特的效能,因此对模块化设计的理论体系进行研究就显得尤为重要。模块化设计主要包括模块划分及合理性评价、模块设计、模块管理等,而模块划分及合理性评价是实施模块化设计的基础及关键所在。因此本文着重研究模块划分方法及评价,同时对模块设计和模块管理也做一定的探讨。本文将模块划分及合理性评价又分为权重指标的确定、原始子模块的聚类以及模块划分方案评价三部分。进行模块划分时,首先是要确定划分的指标或依据,通过对已有文献的研究,结合CXT系列电动葫芦的特点,本文主要是把各子模块的功能相关性、几何相关性、物理相关性等作为模块划分的依据。因此,在模块划分前确定各相关性权重就尤为重要,本文采用的是层次分析法,综合考虑对模块划分时产生影响的各种因素建立层次分析法模型树,通过计算得出各相关性的权重。权重确定后就要进行各初始子模块相关性矩阵的建立和计算,进而得出各种划分方案。本文采用的是模糊聚类分析法。通过各初始子模块之间的功能相关性、几何相关性、物理相关性,得出相关性矩阵,按照不同的阀值进行聚类,并绘制动态聚类图,得到聚类结果。聚类后得到的模块划分方案不是唯一的,对于多种模块划分方案,文中采用灰色关联分析法来优选划分方案。
[Abstract]:With the development of economic globalization, the increasingly fierce market competition, China's equipment manufacturing industry is facing a huge challenge. In order to better adapt to the international situation, improve the technological content of the domestic machinery and equipment, won the domestic and foreign markets, based on the CXT series of electric hoist as the carrier, the research method of modular design. Combined with previous research results, puts forward a set of modular design system.
The idea of modularization in the equipment manufacturing industry prospects, future will be vigorously promoted. The modular design method as a modern design method and a new thought, analysis in the pattern of things, decomposition, mechanism optimization and system restructuring, coordination and other aspects, has its unique performance, it is particularly important so the research on the theory of modular design.
Modular design mainly includes module division and rationality evaluation, module design, module management, and module division and rationality evaluation is the basis and key module design implementation. This paper focuses on the module partition method and evaluation, and also do some research on the module design and module management. The module partition and rationality evaluation to determine the index weight, the original sub module and clustering module partition scheme evaluation of three parts.
Is divided into several modules, the first is to determine the classification index and basis, through the study of literatures, combined with the characteristics of CXT series electric hoist, this paper is mainly the function of each module of the geometric correlation, correlation, correlation between physical as the basis for module division. Therefore, the module division determined before it is particularly important to the the correlation weights used in this paper is the analytic hierarchy process, comprehensive consideration of various factors that influence on the module partition when establishing AHP model tree, obtained by calculating the weight of each correlation.
The establishment and calculation of weights will be carried out after the initial module correlation matrix, then obtains the various classification scheme is adopted in this paper. The fuzzy clustering analysis method. Through the correlation function between each sub module, initial geometric correlation, physical correlation, correlation matrix obtained by clustering, according to different threshold, and dynamic clustering chart and get the clustering results.
The module partition scheme obtained by clustering is not the only one, and the grey relational analysis is used to optimize the partition scheme for multiple module division schemes.
