INVESTIGATION OF SHRINKAGE RELATED LEAKAGE IN CI SAND CASTING - STUDY AND CONTROL USING SIMULATION AND EXPERIMENTAL VALIDATION

In this paper, the design and control of a robotic device intended to stabilize the head and neck of a trauma patient during transport are presented. When transporting a patient who has suffered a traumatic head injury, the first action performed by paramedics is typically to restrain and stabilize the head and cervical spine of a patient. The proposed device would drastically reduce the time required to perform this action while also freeing a first responder to perform other possibly lifesaving actions. The applications for robotic casualty extraction are additionally explored. The design and construction are described, followed by control simulations demonstrating the improved behavior of the chosen controller paradigm, linear active disturbance rejection control (LADRC). Finally, experimental validation is presented, followed by future work and directions for the research.

Future Work

This work presents results of an initial investigation into models and control strategies suitable to prevent vehicle rollover due to untripped driving maneuvers. Outside of industry, the study of vehicle rollover inclusive of both experimental validation and practical controller design is limited. The researcher interested in initiating study on rollover dynamics and control is left with the challenging task of identifying suitable vehicle models from the literature, comparing these models with experimental results, and determining suitable parameters for the models. This work addresses these issues via experimental testing of published models. Parameter estimation data based on model fits is presented, with commentary given on the validity of different methods. Experimental results are then presented and compared to the output predicted by the various models in both the time and frequency domain in order to provide a foundation for future work.

This article provides an assessment of current CFD technology with application to propulsion integration, a definition of research and development needed to extend the technology, and a discussion of numerical error assessment and control. The CFD technology is divided into the elemental areas of the computer system, algorithms, geometry and mesh generation, turbulence modeling, and experimental validation; the current status and major issues in each of these areas are defined. Sources of numerical error are identified and some strategies for determining and controlling these are presented. CFD will have an impact on propulsion integration equivalent to that of the wind tunnel as CFD technology matures. This maturation will lead to a system which integrates the elemental areas of CFD for applications.
