Abstract
With the application of simulation technology in large-scale and multi-field problems, multi-domain unified modeling become an effective way to solve these problems. This paper introduces several basic methods and advantages of the multidisciplinary model, and focuses on the simulation based on Modelica language. The Modelica/Mworks is a newly developed simulation software with features of an object-oriented and non-casual language for modeling of the large, multi-domain system, which makes the model easier to grasp, develop and maintain.It This article shows the single degree of freedom mechanical vibration system based on Modelica language special connection mechanism in Mworks. This method that multi-domain modeling has simple and feasible, high reusability. it closer to the physical system, and many other advantages.
Highlights
With the development of science and technology,product design is becoming more and more complicated
Complex products is the product of cross subject, which will be involved in multiple areas, such as electronics, control, software, machinery, etc
There are some solutions for multidisciplinary modeling, such as multiple domain modeling based on interface and modeling based on high level architecture[1], but these are more or less the problems
Summary
With the development of science and technology ,product design is becoming more and more complicated. Sophisticated product design involves multiple areas and updates frequently. Complex products is the product of cross subject, which will be involved in multiple areas, such as electronics, control, software, machinery, etc. Through multidisciplinary modeling for complex product design, it be modeled in all areas, need a lot of coordination simulation in the overall system level, it has brought a lot of difficulties for simulation modeling of complex product. Multidisciplinary modeling (multi-domain modeling) is a model of different disciplines assembled into a larger simulation model. These areas generally relates to mechanical, control, electronic, hydraulic, pneumatic and other. It developed from a single to multi-domain modeling ,discrete modeling in continuous or discrete domain to hybrid modeling [2], eventually developed into the stage of object-oriented modeling
