Ítem Virtual prototype simulation case study in mechatronic product development based on systems engineering approach(2013-11-20) Carvajal Arango, Ricardo; Mejía Gutiérrez, Ricardo; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Ricardo Carvajal (rcarvaj2@eafit.edu.co); Ingeniería de Diseño - GRIDNowadays consumers are demanding products richer in technologies and associated services -- That is why the link between disciplines, such as Engineering Design and Mechatronics, gets stronger each day, especially, due to the different functionalities and features that should be integrated in products in a more articulated manner -- In order to prepare the future generation of engineers, they should be aware and must know the supporting tools recently available in the market to support and automate these interactions among disciplines -- Regular engineering design approaches, start from requirements understanding and end with a physical prototype, passing by conceptual and detailed design -- Nevertheless, the product design process should allow engineering students to forecast product behaviour and its validation through simulation in early design phases, before physical prototyping -- In some cases, complexity increases as products require the integration of technical systems involving mechanics, electronics and control, among others -- Therefore, design concepts cannot be easily tested using a traditional CAD package that needs a physical prototype for validation purposes -- This article presents a case study using a Systems Engineering approach in academia (with RFLP Requirements/Functions/Logical/Physical) to develop a virtual prototype of a mechatronic product, its simulation and validation against data obtained from the real product -- The RFLP method allows engineers to test designs at early design phases by using virtual prototype and virtual simulation, including behaviour and electronics -- Therefore, design concepts can be validated without having the need to build physical prototypes which implies higher costs and manufacturing time -- From the academic point of view, students can be aware that their design concepts will work properly in the real world by performing enriched simulation processesÍtem Virtual validation of an automated greenhouse irrigation model based on a systems engineering approach(2014-03-27) Mejía Gutiérrez, Ricardo; Zuluaga Holguín, Daniel; Carvajal Arango, Ricardo; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Daniel Zuluaga (dzulua19@eafit.edu.co); Ricardo Carvajal (rcarvaj2@eafit.edu.co); Ingeniería de Diseño - GRIDIn the context of multidisciplinary complex systems design, modelling is a key aspect -- It allows designers to validate designs at early design stages -- Consequently, reducing the uncertainty regarding if the product fulfils the initial requirements, so they can go through the remaining development stages knowing that have found an optimal solution -- In this work, a virtual prototype of an automated greenhouse irrigation system is modelled and compared with the real system implementation, finding some differences and similarities between both system testing approaches -- The intrinsic dependence of experimentation and modelling is also discussed, as sometimes experimental data is needed to feed virtual models
