Electromechanical system knowledge component design method

Abstract

The invention discloses an electromechanical system knowledge component design method, which comprises the following steps: 1, dividing models with different granularity levels according to design requirements and system structure composition; 2, carrying out physical modeling according to the functions and modeling specifications of each hierarchical model; and step 3, performing simulation verification on the modeled model according to product performance indexes. Model development and simulation activities of different granularities and different dimensions of each function module are carried out on electromechanical systems with the same function module and connection relation under a unified physical architecture; hierarchical management is performed on the simulation model or the knowledge component according to the organizational relationship of the physical architecture; a model universal interface and a parameter identification specification are stipulated, and systematicness, normalization and traceability of modeling simulation work of the electromechanical system are realized.

Description

technical field [0001] The invention relates to the field of electromechanical systems, in particular to a method for designing knowledge components of electromechanical systems. Background technique [0002] Aeromechanical system design is a complex system engineering, including many disciplines such as mechanics, solids, fluids and circuits. Therefore, multidisciplinary system simulation based on Amesim and Simulink has become an indispensable design method in the process of electromechanical system design. In the previous system simulation work, the work of model establishment, simulation analysis and model exchange was mainly completed by the designer of the simulation component alone, and the results of the modeling and simulation were reported to the upper-level component designer or professional in the form of tables and reports. chief teacher. Such a modeling and simulation working mode has the following three defects: [0003] 1. Defects in the modeling process ...

Problems solved by technology

[0004] There is no overall layout for the system modeling work, and there is no uniform specification for the modeling process. The modeling of each component is arbitrary, which is reflected in the inconsistent interface and granularity of each component model, which leads to the loss of the purpose of system simulation in the integrated simulation of each component model or computationally inefficient

[0005] 2. Model transmission defects

[0007] 3. Simulation defects

[0008] Due to the lack of test data and some of the test data are not targeted, the establishment and verification of many models cannot be carried out, resulting in relatively low efficiency in model establishment and verification, resulting in poor effect and low accuracy of model use
