Dynamics Characteristic

The main research is the dynamics characteristic of the shock excitation part of electro hydraulic control harmonic aging stress elimination devices. Use the system dynamics knowledge to set up a dynamics model of the shock excitation part. Analyze the transfer function of system and then use MATLAB to draw graphics under the condition of different parameters. Through the simulation graphic's analysis, we can obtain the influence of various parameters on system model, so as to provide a reference for the system optimization. MATLAB is abbreviation of Matrix Laboratory, which is used for algorithm development, data visualization, data analysis and numerical calculation of high-level technical computing language and interactive environment. It is useful for us in modeling and simulation.

Future Work

Sub-sea installation operations require a high level of accuracy and control in order to avoid misalignment and possible collisions between modules on the sea bed. To reduce costs, smaller and lighter construction vessels are now performing these operations. The most critical parts of the operation are lift-off from the deck, passing through the splash zone, and landing sensitive equipment on the sea bed. The hazards are: high dynamic loads, resonance effects, and slack line snap. Therefore, in this study, modeling and simulation are applied to optimize design parameters and develop operational procedures for each operation to reduce risk of failure. Further, the same models can be used in operator simulator training. Modeling and simulation of interactive multi body systems is a rather complex task, involving the vessel as a moving platform, lifting equipment such as cranes and winches, guiding devices, lifting cables and payload behavior in air, all while partly to fully submerged. It is a multi-physics problem involving hydrodynamics, mechanics, hydraulics, electronics, and control systems. This paper describes an approach to link the different models to simulate the operations including interactions between the sub-systems. The paper focuses on the modeling approach used to connect the various dynamic systems into the complete operating system. The work is in its initial phase, and some of the sub-systems models are not complete. The models are described in this paper and will be included in future work. Some initial operational examples are included, to show how the models work together.

Competencias Transversales

The the need for greater participation and motivation of university students in the teaching-learning process has led to the concept of project-based learning. By using this methodology, the student works individually and in groups independently, but under the guidance of the teacher. Furthermore, this methodology allows the acquisition of transversal skills with a high level of mastery in subjects of the last year of undergraduate and master degrees. The objective of this work is the design and application of the project-based learning methodology in the subjects of Bioelectronics and Modeling and simulation of bioelectric systems that is capable of integrating the transversal competences "Design and project" (CT05), "Effective communication ”(CT08),“Understanding and integration ”(CT01),“ Analysis and problem solving ”(CT03),“Innovation, creativity and entrepreneurship ”(CT04) and“ Critical thinking ”(CT09), with high levels of mastery. This methodology has been applied throughout the 2019-2020 academic year in these subjects belonging to the Degree in Industrial Electronic and Automatic Engineering and the Master of Biomedical Engineering, respectively, from the Universitat Politècnica de València. The assessment of the students has been very positive and the acquisition of transversal skills has been very satisfactory.

The increasing complexity of modern systems makes their design, development, and operation extremely challenging and therefore new systems engineering and modeling and simulation (M&S) methods, techniques, and tools are emerging, also to benefit from distributed simulation environments. In this context, one of the most mature and popular standards for distributed simulation is the IEEE 1516-2010 - Standard for M&S high level architecture (HLA). However, building and maintaining distributed simulations components, based on the IEEE 1516-2010 standard, is still a challenging and effort-consuming task. To ease the development of full-fledged HLA-based simulations, the paper proposes the MONADS method (MOdel-driveN Architecture for Distributed Simulation), which relies on the model-driven systems engineering paradigm. The method takes as input system models specified in Systems Modeling Language, the reference modeling language in the systems engineering field, and produces as output the final code of the corresponding HLA-based distributed simulation through a chain of model-to-model and model-to-text transformations. The obtained simulation code is based on the HLA Development Kit software framework, which has been developed by the SMASH-Lab (System Modeling and Simulation Hub - Laboratory) of the University of Calabria (Italy), in cooperation with the Software, Robotics, and Simulation Division (ER) of NASA’s Lyndon B. Johnson Space Center (JSC) in Houston (TX, USA). The effectiveness of the method is shown through a case study that concerns a military patrol operation, in which a set of drones are engaged to patrol the border of a military area, in order to prevent both ground and flight attacks from entering the area.
