Multidisciplinary co-simulation architecture approach

Abstract

The invention relates to a multidisciplinary co-simulation architectural method. Standard or secondary development interfaces and proxy interfaces corresponding to commercial engineering software are independently distributed; interdisciplinary information interaction and interoperation are achieved for the commercial engineering software through a soft-bus platform; the problems that the interfaces provided by the commercial engineering software are unable to be inter-versional and software distributed layout is unsupported during multidisciplinary co-simulation are solved; multidisciplinary co-simulation availability of the commercial engineering software is enhanced. According to the method, the commercial engineering software are organically connected through an HLA / RTI (high-level architecture / run-time infrastructure) soft-bus platform, thus multidisciplinary co-simulation can be better supported, and design efficiency of and confidence level of a complex system are effectively ensured; software sub-systems are all independent in the physical layer, thus the amount of the sub-systems is convenient to increase and extensibility is good.

Problems solved by technology

[0005] The simulation of the point-to-point structure mode mainly realizes the two-way transmission and interaction of data through the data interface between the software. Since the data interface of each different version of the simulation software can only support the data interface of other software of the corresponding version, it leads to the simulation model. The reusability is very low. In addition, when the low-level commercial simulation software wants point-to-point simulation, it must be installed on the same operating platform and cannot be distributed. Although some high-level commercial simulation software has added the function of remote communication , but it is still not perfect, so the point-to-point simulation cannot meet the requirements of co-simulation for complex product design;

[0006] Due to the lack of an effective data filtering mechanism and customized message customization methods, the network structure model has a large amount of redundant data in the network, and its real-time and reliability are difficult to guarantee, so it is not suitable for complex product design. co-simulation problem;

[0007] The soft bus structure mode separates the entire co-simulation from the physical level based on the simulation method of the soft bus. Each subsystem communicates and interacts with each other through the soft bus, which can ensure the reusability of each subsystem and the characteristics of distributed layout. However, due to the insufficient openness of commercial engineering software, in the existing soft bus multidisciplinary collaborative simulation, the independent connection between commercial engineering software and the soft bus platform has not been fully realized. For example, ADAMS grafts the model to MATlab through its control module. / Simulink, and then exchange information with the soft bus platform through Simulink, which leads to low reusability of the simulation model, and also limits its distributed layout, so the interface development between commercial engineering software and soft bus is very difficult Focus on realizing multi-disciplinary co-simulation;

[0008] To sum up, at present, the interfaces provided by commercial engineering software in multidisciplinary co-simulation cannot cross versions and do not support software distributed layout.
