Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the examples.

[0046] The invention relates to a distributed all-digital co-simulation system. In particular, it involves the use of distributed and client / server structures in the coupling system design and iterative verification stages to realize full digital co-simulation in compliance with the FMI (Functional Mock-up Interface) standard. The distributed all-digital co-simulation system consists of three parts: the distributed co-simulation subsystem client mainly realizes the digital simulation calculation of each subsystem, the distributed co-simulation result visualization client mainly realizes the simulation result visualization, and the distributed co-simulation service The terminal mainly realizes the synchronous control of co-simulation. The system realizes the co-simulation of heterogeneous system models, realizes co-simulation across geographic regions, and adopts black bo...

Abstract

The invention relates to a distributed full-digital joint simulation system and method, and particularly aims at realizing full-digital joint simulation according with an FMI standard by using distributed and client / server structures in coupling system design and iterative verification stages. The system consists of three parts: a distributed joint simulation subsystem client, a distribution jointsimulation result visualization client and a distributed joint simulation server, wherein the distributed joint simulation subsystem client is mainly used for realizing digital simulation calculationof each subsystem; the distributed joint simulation result visualization client is mainly used for realizing visualization of simulation results; and the distributed joint simulation server is mainlyused for realizing synchronous control of joint simulation. According to the system and method, joint simulation of heterogeneous system models is realized, joint simulation of cross-geographic areasis realized, and black box-mode simulation is adopted so that the intellectual properties are protected.

Description

technical field [0001] The invention relates to digital system simulation technology, in particular to a distributed all-digital co-simulation system and method. Background technique [0002] Model-based system engineering is more and more used in the V-shaped product development process. Digital modeling and simulation can comprehensively verify and optimize product design schemes, significantly shortening the development cycle and reducing costs. Driven by the development of the new generation of aircraft electromechanical and energy integration, the simulation requirements have changed from a single subsystem and a single discipline to the integration of control subsystems, hydraulic subsystems, fuel subsystems, environmental control subsystems, and energy distribution subsystems. Multi-system, multi-disciplinary co-simulation development. The existing co-simulation is mainly aimed at two kinds of simulation tools, and realizes data exchange by providing an interface bet...
