Modeling Hydraulic Systems Behavior Using SysML Presented to: Dr. Gary May & Dr. Chris Paredis By: Arnaldo J. Colón-López Universidad del Turabo, P.R. Mechanical Engineering Fifth Year SRL August 3, 2005

SRL 14 Overview Motivation & Objectives What is SysML? HAL System Overview Approach Results Conclusions Summary

SRL 15 Motivation & Objectives How can we support the simulation of system models?  Save the knowledge about the model in a standard language  Create the model once, then reuse rather than recreate the model System Engineers need a standard language to facilitate systems design through the use of reference libraries in SysML. Generate reference and simulation library of components. Create system simulations automatically from configurations of reference models. Make links to simulation models Save money, time and effort

SRL 16 System Modeling Language “SysML” SysML is a profile and extension of the Unified Modeling Language. Supports the verification and analysis of complex systems. Improves the ability to exchange systems engineering information amongst tools Focuses on engineering systems.

SRL 17 HAL System Overview The Hydraulic Actuated Lifter was designed and build in the Intelligent Machine Dynamics Laboratory at Georgia Tech. HAL was designed by two IMDL students, Mimics a forklift truck. Primary purpose is to serve as an educational tool. HAL is constrained by a linear track for safety reasons.

SRL 18 Approach Learn about SysML Develop the hydraulic components library. Describe the HAL system using the SysML tools. Find the best diagram for the system behavior representation. Generate the links for the simulation and reference models. Build the simulation using the Dymola Software. Test the entire design process.

SRL 26 Conclusions SysML is a good language for defining reference models.  SysML defines the relation between the reference and simulation models once  Reuse the reference model often  Saves time & resources.

SRL 27 Summary SysML is a profile and extension of Unified Modeling Language. SysML was used to provide a standard modeling language for systems engineering to analyze the HAL System. Main SysML Diagrams are: Parametric, Class and Structure diagrams. Artisan Real-Time Studio with SysML supports the representation of system behavior.
