【摘要】 基于功能-行为-结构映射的机构系统概念设计模型,通过与功能相关联物理行为的综合,实现功能到结构的转换;通过分析执行动作形式,定义了有效工作时段的动作形式;在确定工作原理的条件下,建立了构造功能与有效工作时段动作映射矩阵的方法.根据专家经验,对能实现一个功能的所有有效工作时段动作进行评价,建立了从整个工艺动作过程的动作方案,集中寻求最优化有效工作时段动作方案的评价规则、数学模型和求解方法,并给出实例.更多还原

【Abstract】 The conceptual design of a mechanism system based on function-behavior-structure(FBS) model carries out the transformation from function to structure via synthesis of physical behavior relating to the required functions.Motion forms of working stroke were defined through analysis of executive movement.A method to construct the mapping matrix from function to motion of working stroke was established provided that the principle of work is determined.All the possible motion solutions of working stroke to complete one same function were evaluated on the basis of expertise.In order to seek an optimal scheme(among) those possible motion solutions of working stroke for the whole behavior process,an evaluation criteria,mathematical models and solution procedure were established.Finally,one example was given to demonstrate the presented method.更多还原
