【摘要】 复杂机电系统是现代科技发展的必然产物,其设计与开发对提高产业国际竞争力、增强国家经济实力和国防实力具有重要的战略意义。复杂机电系统的主要特征和功能都是从物质流、能量流的信息流中体现出来的,物质流是能量流的载体,同时又在能量驱动下产生运动,二者都是在信息流控制与高度协同下进行。但各子系统间通过物质流、能量流和信息流的相互传递和转换实现特有功能的同时,流的属性及类型变化会对其他流产生负作用,这些负作用会使流无法协同工作,造成不期望流的出现,造成系统在运行中表现出功能缺陷、功能减弱、功能失效或工况奇异等诸多问题。因而急需一种系统化问题分析及求解的理论与工具以快速高效的解决复杂机电系统中的多流问题。论文的主要工作包括以下几方面内容:1.建立多流问题网络过程模型。从复杂机电系统多流之间相互作用的负作用入手,对其引起的问题流进行流分析,建立流缺陷模型。研究各个流之间的相互传递转换和演变关系,挖掘并分析多流之间存在的多流问题,建立基于流结构信息的多流问题分析模型,形成揭示复杂机电系统多流问题的衍生机理。依据可拓理论相关分析方法确定多流问题间的关联性,并利用相关网将其转化为网的形式,从而构建多流问题网络过程模型。2.将多流问题网转化为冲突网。通过对多流问题的深入分析,提取出关键的多流问题,将其转化为冲突。深入分析组成冲突的控制参数和评价参数,将其ENV模型化,并构建冲突网,分别采用定性分析和定量计算的方式对冲突进行重要度排序,得到关键冲突。3.利用TRIZ工具进行关键冲突的求解。利用TRIZ工具对冲突网进行求解,对于其中难求解的冲突,应用ARIZ算法进行求解,将得到的解决方案组合进行优化得到最优方案。4.对工程机械线香捆扎机进行创新设计。从工程实际出发,分析捆扎过程中常见的问题,应用多流问题网络过程模型进行创新设计,提出了新的概念解决方案,验证了过程模型的有效性。更多还原

【Abstract】 Complex electromechanical system is the inevitable product of the development of modern science and technology.Its design and development is of strategic importance for improving the international competitiveness of industry,enhancing the national economic strength and national defense strength.The main features and functions of complex electromechanical system are reflected in the information flow from material flow and energy flow.The material flow is the carrier of the energy flow,and at the same time,it produces the movement under the energy drive.Both of them are carried out under the information flow control and the high degree of cooperation.However,through the mutual transfer and conversion between each subsystem through the material flow,energy flow and information flow to realize its special function,and at the same time,the change of attributes and types of flow will have negative effects on other flows.These negative effects will make the material flow,energy flow and information flow are difficult to be highly coordinated,which results in many problems,such as functional defects,function weakened,function failure or queer operating conditions,etc.Therefore,a systematic theory and tool for problem analysis and solution is urgently needed to solve the multi-flow problems in complex electromechanical systems quickly and efficiently.The main work of this paper includes the following aspects:1.Set up a network process model for multi-flow problems.Starting from the negative effect of the interaction between the multi-flow of complex electromechanical systems,the flow analysis is carried out to the problem flow caused by the negative effect,and the flow defect model is established.We study the relationship of transfer,transformation and evolution among different flows,excavate and analyze the multi-flow problems among multi-flow,and establish the analysis model of multi-flow problems based on flow structure information,and form the derivation mechanism to reveal the multi-flow problems of complex electromechanical systems.The correlation between multi-flow problems is determined according to the correlation analysis method of extension theory,and use the correlation net to transform it into the form of network.Thenetwork process model of multi-flow problem is constructed.2.The multi-flow problem network is transformed into a conflict network.Through the in-depth analysis of the multi-flow problem,the key multi-flow problem is extracted and transformed into a conflict.In depth analysis of control parameters and evaluation parameters that constitute conflict,ENV is modeled,and conflict network is constructed.The importance of conflict is sorted by qualitative analysis and quantitative calculation,and key conflicts are obtained.3.Use the TRIZ tool to solve the key conflict.The TRIZ tool is used to solve the conflict network.The ARIZ algorithm is used to solve the conflicts which are difficult to solve,and the optimal solution is obtained by the combination of the solutions.4.Innovative design of mechanical engineering incense bundling machine.Starting from the engineering practice,the common problems in the process of strapping are analyzed.Based on it,a new conceptual solution is put forward by applying the multi-flow problem network process model,which validates the validity of the process model.更多还原
