【摘要】：机械产品的系列化和标准化是现代化工业发展的要求与结果。如何科学、快捷的进行产品系列化设计,寻求先进的系列化设计方法对于产品系列化具有理论价值与实际指导意义。本文试图对于非标机械产品系列化设计进行一些基础性的研究与探讨,尝试提出采用建立非标产品的系列化设计准则(简称系列化准则)的方法指导系列化设计。非标设计一般以单台套产品设计为主,系列化程度较低,但随着技术发展,非标产品系列化也越来越多。在单一产品的基础上,设计开发类似的产品,基于已有产品的扩展设计,都属于本文研究的范畴。相似理论具有很高的工程应用价值,相关研究持续不断,主要集中在系统间的模型试验、系统间的相似度量及其工程应用,产品系列化研究较少。周美立教授对相似理论进行了系统深入的研究,取得了系列研究成果,研究了产品系列化设计问题,将相似系统分为精确相似、可拓相似和模糊相似,对系列化设计进行了系统地描述,并给出了基于基型扩展计算公式。本文旨在借助相似理论的概念,探索更为简洁实用的产品系列化设计方法,基于相似第二定理,把相似准则直接或有条件的转化为机械产品系列化设计准则,利用设计准则得到产品的系列化设计参数,为繁琐的系列化设计提供科学快捷的方法。本文基于两个相似体之间的相似准则,研究非标机械产品系列化设计准则的建立方法。首先建立了非标机械产品单一零部件系列化设计准则,并将其推广到单一机械系统与复杂机械系统。提出了复杂系统下采用主系统、主参数具有工程使用价值的系列化设计方法。最后给出了工程应用实例,采用提出的理论方法,对旋转雾化系统建立了各子系统的系列化准则,并初步给出了系列化设计结果。该研究对于新产品开发,尤其是在一定基础上进行系列化开发具有指导意义。
[Abstract]:The serialization and standardization of mechanical products are the requirements and results of the development of modern industry. How to carry on the serial design of the product scientifically and quickly, and seek the advanced seriation design method has the theoretical value and the practical guiding significance to the product seriation. This paper tries to make some basic research and discussion on the serial design of non-standard mechanical products, and tries to put forward the method to guide the series design with the method of establishing the series design criterion of non-standard products (the series criterion). The design of non-standard products is mainly based on the product design of single platform, and the seriation degree is low, but with the development of technology, the series of non-standard products is more and more. On the basis of a single product, the design and development of similar products, based on the expanded design of the existing products, belong to the scope of this paper. The similar theory has a very high value of engineering application, and the related research is continuous, mainly in the model test between the systems, the similarity measure between the systems and the engineering application, and the product seriation research A systematic and in-depth study of similar theory has been carried out by Professor Zhou Meili, and the series of research results have been obtained. The problems of serial design of the product are studied. The similar system is divided into the exact similarity, the extension similarity and the fuzzy similarity, and the seriation design is systematically The base-based extension calculation is also given. The purpose of this paper is to explore a more concise and practical product seriation design method with the aid of the concept of the similar theory. Based on the similar second theorem, the similar criterion is directly or conditionally converted into the series design criterion of the mechanical product, and the serial design parameter of the product is obtained by using the design criterion. The number, which provides a scientific and quick side for the tedious series design Based on the similarity criterion between two similar bodies, this paper studies the construction of the series design criteria for non-standard mechanical products. In that first place, a series design criterion of the single part of the non-standard mechanical product is set up, and it is spread to a single mechanical system and a complex machine. The main system is put forward in the complex system, and the main parameters have the seriation of engineering use value. In the end, the application example of the project is given, and the series criterion of each sub-system is set up for the rotary atomization system, and the seriation of the series is also given. The results of the study are as follows: the new product development, especially on a certain basis, has the meaning of the series development.
