Research On Implicit Coupling Reasoning And Transformation Mechanism Of Complex Electromechanical System Based On Flow Analysis

The strong coupling between the functions of complex electromechanical systems is the main feature of complex electromechanical systems and also the main difficulty in the design process.Therefore,the analysis of functional coupling between complex mechanical and electrical equipment subsystems to identify the design parameters that affect the coupling function,through reasonable means to change or replace the coupling of design parameters to reducing the complexity of the system is an important means to improve the strong coupling between complex electromechanical system functions.For the coupling of functional problems in the design of complex electromechanical systems,the main contents of this paper are as follows:1.A coupling parameter search method based on flow analysis is proposed.This paper traces the nature of the input and output of the entire system and studies in depth the functional structural features of complex electromechanical systems.Analyze the total function of the system input/output material flow,energy flow and information flow,establish the mapping process from system effect chain to function chain,and then combine the effect-structure correspondence to build the system design structure matrix and transform it,so as to intuitively express the relationship between the parameters within the system.2.A decoupling process model based on combination of TRIZ theory and clustering is proposed.After clarifying the coupling relationship of parameters in complex electromechanical systems,coupled-parameter clustering methods are used to reduce the coupling in the system.In order to find the direction of the parameter module,the material-field model and conflict theory coupling in TRIZ theory are applied.Finally find the decoupling module that meets the requirements in the available resources of the system.3.Finally,taking the automatic follow-up system of farm machinery loader as an example,using the method described in this paper to analyze the coupling relationships in the system and improve it.Completed the hardware and software design of the prototype model.The performance of the prototype is evaluated and analyzed by experiments,and the effectiveness of the proposed method is verified.
