Semi-physical Modeling and Simulation for Industrial Product Design Based on X Language

With the increasing complexity of research and development in industrial product (IP), systems engineering methods have been widely adopted, particularly the model-based system engineering (MBSE) method. Semi-physical simulation techniques can significantly expedite the transition from an IP model to the final prototype, thereby ensuring a higher success rate in IP design. However, the mainstream MBSE modeling language, SysML, lacks support for simulating semi-physical scenarios. Therefore, it becomes necessary for the system engineer to integrate semi-physical simulation tools. To address this issue, this paper proposed a semi-physical modeling and simulation method for IP based on the X language, which is a system modeling and physical modeling integrated modeling language. The semi-physical simulation of the X language semi-physical model is derived by the XDEVS-simulator. Compared to existing SysML-based methods that necessitate the use of different software tools at various stages, the X language-based method enables system engineers to employ a unified language and software throughout modeling, digital simulation and semi-physical simulation phases in IP design. This effectively reduces complexity and enhances efficiency in IP design. Finally, a case study involving mechanical arm design is used to validate the effectiveness of the proposed method.
