（ 二○○六年六月 Mechanical products of modern design methodology and the programme trends Summary: According to the current domestic and international product design, mechanical design scholars of the main features of thinking, product design methods summarized as a systematic programme, modular structure, based on product knowledge and wisdom of the four types. That the four methods of the organic link between features and its proposed product design computer programmes to achieve endeavors. Keyword: mechanical products; Programme design; Trends Introduction With The rapid development of science and technology, the functional requirements of a growing number of products and complexity increase, shortened life expectancy, upgrading speed, the design of the products, particularly machinery products programme design are in urgent need .At present, computer-aided product design drawings, design calculations, processing manufacturing, production planning has been a relatively broad and in-depth study, but results and product development programme of the early computer-aided design falls far short of the design requirements. To this end, the author read a lot of literature on the basis of summarizing the design scholars and the methods used for programme design, and discussed ways of the organic link between the computer and mechanical products for programme design trends. Under the current design scholars and mechanical products used in the design of programmes of the main features of methods, the modern design of the programme approach can be summarized as the following four types: 1. Systematic design methodology The main features of a systematic design methodology: design by several design elements as a system, the independence of each design element, the presence of various elements of the organic link between each element, and is layered, all elements of the design System design can achieve the required tasks. Systematic d
