Research On The Series Design Criterion And Engineering Application Of Non-standard Mechanical Products

Serialization and standardization of the mechanical product is the demand and result of the development of modernization industry. It is worthy theoretically and directive practically for product serialization to carry on the product serialization design scientifically and quickly and search advanced serialization design methods. This article tries to do some basic investigates for the non-standard mechanical product, and present the method that established the serialization design criterion (simplified as serialization criterion) to direct the serialization design. The degree of the non-standard product serialization is low. The non-standard product design usually focus on single item. With the development of the science and technology, more and more serialization of non-standard product design is needed. The article will research the serialization of non-standard product, including developing similar products based on a single designed product, and extending design of non-standard products from existed products, etc.The similarity theory is with high engineering application value, the correlation research of it is continuing, and mainly focus on the model experiment and the similarity measurement among the system and its engineering application. However the research of the product serialization is less. Professor Zhou Mei-li researched the similarity theory systemically and thoroughly and got a series of research conclusion. The article studied the product serialization design, the similar system was divided into the precise similar, topological similar and fuzzy similar, the serialization design was systemically described, and the extended calculating formula based on the archetype was given. This article aim to explore more concise and applied product serialization design method in virtue of the similarity theory. The similarity criterion is directly or conditionally converted into serialization design criterion of the mechanical product based on the second Similarity Theorem, and then the serialization design parameter of product can be gotten by the similarity criterion. It is a scientific and quick method for the complex serialization design.Based on the similarity criterion between two similar products, the article research the establishing method of the similarity design criterion of the non-standard mechanical products. Firstly, The series design criterion is established for the single part of the non-standard mechanical product, and then is extended to the single and complex mechanical system. The series design method with main system and main parameter is put forward, and it is valuable for the complex mechanical system. Finally, An engineering applying was exampled. Using the given theory and measures, the similarity criterion of every subsystem for the Rolling Pulverization Powders Manufacturing Equipment was established, and the primary serialization design results were given out. The study is instructional for the new product development, especially for the serialization design on the base of made product.
