Application of Power Electronic Circuitry for Elimination of Flywheel in Process Machines
American Journal of Electrical Power and Energy Systems, 2019Co-Authors: Vasant M. Jape, Hiralal M. Suryawanshi, Jayant P. ModakAbstract:It is felt highly probable to eliminate flywheel from the design of any process machine in general and for process machines with a certain demand torque characteristics in particular. It is felt that by proper interfacing of power Electronic devices this may be possible. Elimination of flywheel from process machines helps reducing torsional vibrations in the power transmission system of any process machine. This should reduce fatigue in the components of power transmission system thereby prolonging equipment functional failure. Down time will be much less and profit earnings through uninterrupted production would be high. This paper proposes a convenient power Electronic Circuitry with reasonable control approach for the flywheel replacement of an induction motor for which it is necessary to generate supply torque at motor shaft exactly equal to demand torque. To meet this requirement, demand torque characteristic is sampled at 25 msec. In proposed solution to this problem, the torque requirement at every sample is met by adjusting the firing angle of thyristors which in turn adjusts the supply voltage at motor terminals. Depending on supply frequency the sampling period for demand torque characteristic may be varied. The present paper has a focus of evolving the details of functional feasibility of this concept only.

Embedding Electronic Circuitry into a metal matrix via ultrasonic additive manufacturing: material considerations and process development
2019Co-Authors: Alkaios Bournias-varotsisAbstract:Ultrasonic Additive Manufacturing (UAM) is a hybrid metal additive manufacturing process, based on the layer-by-layer ultrasonic welding of thin metal foils and the periodic CNC machining of the bonded layers to achieve the desired three-dimensional geometry. Bonding in UAM occurs in the solid state and at low temperature, making UAM a potential technology for embedding Electronic Circuitry into metal structures.Printed Electronics (PE) is a family of processes that can fabricate Electronic Circuitry and components by directly dispensing functional materials onto a substrate. PE technologies have a high potential for integration with additive manufacturing processes, as they both follow similar basic manufacturing principles. Such integration can enable the fabrication of multi-functional parts with embedded Electronic Circuitry. [Continues.]

Ultrasonic Additive Manufacturing as a form-then-bond process for embedding Electronic Circuitry into a metal matrix
Journal of Manufacturing Processes, 2018Co-Authors: Alkaios Bournias-varotsis, Ross J. Friel, Daniel S. EngstrømAbstract:Ultrasonic Additive Manufacturing (UAM) is a hybrid manufacturing process that involves the layer-by-layer ultrasonic welding of metal foils in the solid state with periodic CNC machining to achieve the desired 3D shape. UAM enables the fabrication of metal smart structures, because it allows the embedding of various components into the metal matrix, due to the high degree of plastic metal flow and the relatively low temperatures encountered during the layer bonding process. To further the embedding capabilities of UAM, in this paper we examine the ultrasonic welding of aluminium foils with features machined prior to bonding. These pre-machined features can be stacked layer-by-layer to create pockets for the accommodation of fragile components, such as Electronic Circuitry, prior to encapsulation. This manufacturing approach transforms UAM into a “form-then-bond” process. By studying the deformation of aluminium foils during UAM, a statistical model was developed that allowed the prediction of the final location, dimensions and tolerances of pre-machined features for a set of UAM process parameters. The predictive power of the model was demonstrated by designing a cavity to accommodate an Electronic component (i.e. a surface mount resistor) prior to its encapsulation within the metal matrix. We also further emphasised the importance of the tensioning force in the UAM process. The current work paves the way for the creation of a novel system for the fabrication of three-dimensional Electronic circuits embedded into an additively manufactured complex metal composite.
