- In this work, we have developed an automated method for creating multibody models in the Robotran software from assemblies designed in SolidWorks, a Computer-Aided Design (CAD) software widely used in industry. The main objective of this method is to facilitate and accelerate the conversion of CAD models into dynamic models that can be utilized in Robotran. The proposed method revolves around two main modules: the first, named pyswtools, is dedicated to preprocessing data extracted from SolidWorks, such as geometries, mass properties, and assembly configurations. This data is then structured into a specific format through a JSON file. The second module, sw2robotran, uses this data to automatically generate the multibody system (MBS) model, defining the different bodies of the system, their properties, and interactions with other components. This model is then ready for dynamic simulation in Robotran. The results obtained demonstrate the feasibility and efficiency of this approach for creating complex multibody models, paving the way for increased automation in the modeling process. The identified areas for improvement include the integration of a deeper physical dimension into the module, expanding compatibility with other CAD software, and adapting to a wider variety of mechanical configurations. These improvements aim to enrich the user experience and extend the method’s capabilities, making it more versatile and suited to the needs of industrial applications. In conclusion, this work represents a significant advance in the field of dynamic simulation by simplifying the modeling process for multibody systems and increasing the accessibility of simulation tools for engineers and researchers. Ultimately, the possibility of directly integrating this method into the Robotran software could offer a comprehensive solution for the analysis and optimization of complex mechanical systems.
