A casting mould for rapid tube hydroforming prototyping
(AGH University of Science and Technology Press, 2020) Kochański, Andrzej Witold; Sadłowska, Hanna
In recent years, hydroforming has clearly expanded its range of industrial applications due to the growing interest in products which combine high strength with low weight. A current limitation of this technology was its economically justified production volume since the costs of producing tools eliminates the possibility of using hydroforming technology in prototype and single part production. The paper presents a freshly patented solution that allows for single part hydroforming. The new technology combines traditional hydroforming machines with a new approach to tool production. The new rapid die is made quickly and cheaply. The use of materials known from the production of foundry moulds causes the die to deform during hydroforming, but it is a controlled deformation. Thanks to the use of numerical modelling, the deformation of the mould cavity is predicted and taken into account at the design stage. The article presents important issues that need to be considered in the design of this innovative process.

Hardware and software architectures for reconfigurable time-critical control tasks
(2007) Piłat, Adam Krzysztof; Grega, Wojciech
The most popular configuration of the controlled laboratory test-rigs is the personal computer (PC) equipped with the I/O board. The dedicated software components allow to conduct a wide range of user-defined tasks. The typical configuration functionality can be customized by PC hardware components and their programmable reconfiguration. The next step in the automatic control system design is the embedded solution. Usually, the design process of the embedded control system is supported by the high-level software. The dedicated programming tools support multitasking property of the microcontroller by selection of different sampling frequencies of algorithm blocks. In this case the multilayer and multitasking control strategy can be realized on the chip. The proposed solutions implement rapid prototyping approach. The available toolkits and device drivers integrate system-level design environment and the real-time application software, transferring the functionality of MATLAB/Simulink programs to PCs or microcontrolers application environment.

Przetwarzanie i analiza sygnałów w dedykowanym środowisku szybkiego prototypowania regulatorów dla silników elektrycznych
(Wydawnictwa AGH, 2009) Piłat, Adam Krzysztof; Piątek, Paweł; Marchewka, Dariusz; Pauluk, Mariusz
One of the most interesting application of the microprocessor based systems is control of the electric motor by the 8-bit microcontroller with simultaneous data acquisition via USB. The developed solution is an innovative application in the field of universal motor controllers. The most important features of this solution are: low cost, application of digital control and diagnosis algorithm. In the case of application to devices with variable torque the developed system allows to realize a wide range of research including identification, state estimation and synthesis of the optimal control strategy.

Rapid prototyping of water nozzles using CFD modeling and 3D printing results
(Wydawnictwa AGH, 2023) Buksa, Dominik; Madejski, Paweł; Karch, Michał
In recent years, there has been greater interest in rapid prototyping methods employed in various industries. Prototypes are increasingly often made using 3D printing technology, which is mainly due to the relatively low costs of developing and producing such a structure and the short time needed for their physical production. The work presents the possibility of using rapid prototyping techniques, such as water propulsion nozzles. They are mainly used in the energy industry, e.g. for the production of water mist in jets or condensers. Such nozzles enable the formation of a stream, and its range and efficiency depend on the design requirements. CFD (computational fluid dynamics) tools and 3D printing will be used to assess the nozzle’s effectiveness. A 3D printer based on FDM technology was used to produce nozzle prototypes. The CFD results were verified with experiment. Analyzes for four different nozzle shapes are presented and the discrepancies between the results of the initial experimental and numerical analyses are explained. To indicate the imperfections resulting from 3D printing, a 3D scanner was used to show the internal cross-section of the nozzle. The research conducted indicates the significant potential of 3D printing in rapid prototyping and its effectiveness in creating functional models for various engineering applications.
