【摘要】：当前由功能设计得到的产品原理解能否满足功能要求,缺少有效的评判方法,导致设计工作的反复和资源的浪费。通过功能与流之间的关系,揭示了流是表征功能能否实现的重要依据。依据原理结构进行AMESim建模,在结构层上描述了流的传递关系,利用因果序理论建立因果关系网,并据此判断流是否能够实现转换;利用隶属函数确定客户需求和流之间的关系,通过对隶属度划分满意度区间,从而确定流的合理范围;进而提出了一种两级评价法用来判断原理解的可行性。最后以扣圈机验证上述方法的有效性和实用性,并通过AMESim软件进行定量仿真验证所提方法的正确性。
[Abstract]:At present, the original understanding of the products obtained from the functional design can meet the functional requirements, and the lack of effective evaluation methods leads to the repetition of the design work and the waste of resources, and through the relationship between the function and the flow, This paper reveals that the flow is an important basis for the realization of the representation function. According to the principle structure, the AMESim modeling is carried out, the transfer relation of the flow is described on the structure layer, the causality relation network is established by using the causality order theory, and the flow can be converted according to the theory of causality order. The relationship between customer demand and flow is determined by membership function, and the reasonable range of flow is determined by dividing the satisfaction interval of membership degree. Then a two-level evaluation method is proposed to judge the feasibility of the original understanding. Finally, the validity and practicability of the above method are verified by a coiling machine, and the correctness of the proposed method is verified by quantitative simulation with AMESim software.
