抽象的多学科复杂机电系统涵盖了力学，电子，控制和软件等学科。提高的复杂性使得为复杂的机电一体化的自动设计实施了高度挑战性。分解整体功能以获得功能结构和原理解决方案的有效方法是为了有效的创意设计。提出了一种混合方法来自动化包含三个主要步骤的功能分解过程。首先，总体功能将根据定性处理推理自动分解为多种功能效应。然后，基于支持函数对每个功能效应进行物理效应分解。对于找不到合适的物理效果的功能，提出了向后搜索分解以找到其多键函数网络。分解过程是用SYSML实现的，并通过汽车引擎示例进行了说明。进行了分析以显示所提出的方法的性能。
ABSTRACT Multidisciplinary complex mechatronic systems span disciplines such as mechanics, electronics, control and software. Increasing complexity makes the implementation of automated design for complex mechatronics highly challenging. An effective method for decomposing an overall function to obtain the function structure and principle solution is needed for efficient creative design. A hybrid approach is proposed to automate the process of functional decomposition which contains three main steps. First, an overall function is decomposed to several functional effects automatically based on qualitative processing reasoning. Then the physical effect decomposition is conducted for each functional effect based on the support functions. For the functions for which a suitable physical effect cannot be found, a backward search decomposition is proposed to find a multichain function network for it. The decomposition process is implemented with SysML, and illustrated through an automobile engine example. An analysis is given to show the performance of the proposed method.
