摘　　要：研究了概念设计过程的发展 ,归纳出瀑布模型、原型模型和喷泉模型三种模型 ,并提出了平面螺旋模型。为便于计算机实现 ,提出了设计方案生成的空间螺旋模型。详细讨论了概念设计的设计要求、初始方案生成等关键问题 ,强调设计要求分析要注意功能的条件性和主次关系。与以往功能分解和功能匹配呈明显先后顺序、相互割裂不同 ,提出了功能分解与功能匹配是呈螺旋上升交替进行的观点。最后通过油田修井机系统设计实例 。Waterfall model, prototyping model and fountain modal were concluded based on current development of conceptual design process. Planar spiral model of conceptual design progress, and spatial spiral model of design scheme generation progress, suitable to computer aided conceptual design were proposed based on current conceptual design progress model. The key problems,including the design requirement of conceptual design process and the establishment of original scheme,were discussed in detail. In design requirement analysis, the condition and relationship of functions were specially emphasized. The function structure establishment and the searching for solution were simultaneously alternately processed, while they were isolated in current research. Finally, above models and thought were proved and illustrated by an actual design case of an oil field machine.
