中文摘要:基于可拓理论提出了机械设计方案的可拓评价方法。基于物元模型和可拓关联度进行机械设计方案决策。根据专家实际经验知识建立期望设计方案的物元模型和备选设计方案的物元模型,然后通过可拓关联度直接评价方案的优劣,关联度是评价设计方案接近期望方案(理想方案)的度量,关联度越大,设计方案接近期望方案就越好。实例表明基于可拓理论的机械设计方案评价是合理的。

Abstract: An extended evaluation method of mechanical design schemes was proposed by means of extension theory. Based on the matter-element model and extended relation degree, the extended evaluation method can carry out the decision-making of machine design schemes. The matter-element model of the expected design scheme and the matter-element models of alternative design schemes were established according to specialists' practical experiences, and then the quality order of schemes was evaluated by the extended relation degree. The relation degree is the measurement index to evaluate how the design scheme is close to the expected one (ideal scheme). The bigger the relation degree is, the better the close degree between the design scheme and the expected scheme is. Finally, the rationality of evaluation in mechanical design schemes was demonstrated through illustrations.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
