摘　　要：为了消除工程设计中的不精确性,在概念设计阶段采用了空间缩小方法,进一步缩小设计空间范围,采用偏好结构表示对给定的设计变量空间和性能变量空间的偏好程度,定量关系表示设计变量空间,通过区间传播定理计算出设计空间到性能空间的映射,找到满足性能需求变化的设计求解范围,消除了不可行的设计子空间和不确定影响因素.以湿式多盘制动器的概念设计为例验证了该方法的正确性,它适用于多目标设计系统.To eliminate the inaccuracy of engineering design,using a space narrow method in the conceptual design phase,further narrowed the scope of the design space.Preference structure was used to express a given design variable space and performance space preference variable.Quantitative relationship showed design variable space.The range of communication design space to performance space mapping was calculated with the interval propagation theorem.The design solution range met the changing needs of the performance was found.Unfeasible sub-space and uncertain factors was eliminated.Wet multi-disc brakes with the concept of design as an example that the method is correct,it is suitable for multi-objective design system.
