基于Modelica多领域物理系统云仿真的研究

摘要

In order to solve problems such as uncapable of achieving consistency and sharing storage between model library and data resources, uncapable of dividing the functions of modeling and solving as well as improving the optimization of multi-domain simulation, cloud computing concepts and methods are introduced and a multi-domain physical system cloud modeling and simulation platform are established. This paper explains the basic solution process of the platform so as to realize the security sharing, the optimization and reuse of model resources, computing resources and data resources of this system. Finally, feasibility analysis of this system is also made.%为解决难以实现模型库及数据资源的一致性与共享存储、未能实现建模与求解的功能划分以及多领域仿真优化问题求解效率低的问题，引入了云计算理念和方法，建立了多领域物理系统的云端模型及仿真平台，阐述了该平台的基本求解过程，这样可以实现系统中模型资源、计算资源和数据资源的安全共享、优化及重用，并对系统的可行性作出了分析．
