The integration method research of MSL and collaborative simulation platform

This article describes two multi-disciplinary modeling and simulation approaches of complex products, points out the language advantage of physical simulation modeling language modelica. By describing the class structure of the language, in particular, the structural characteristics of the equation, It summarizes the modelica language modeling process, and makes analysis for the interpreter and the solver. It graphically details the architecture, hierarchical modeling, high level modeling tools of collaborative simulation platform COSIM. Against the language specific equation expression principle and the characteristics of simulation platform, the integration method of language and platform was creatively proposed, and the key technologies are needed.
