The present invention relates to a thermal device comprising at least one heat exchanger and at least one heat source and/or heat sink. The thermal device in the invention is designed as a combination of the first thermal device based on a vapor-compression principle contained the first heat transfer medium, and the second thermal device based on elastocaloric principle contained the second heat transfer medium. At least one deformable heat exchanger made of elastocaloric material is common to both thermal devices.

COBISS.SI-ID: 15315739During the production of torsion bars, two different mechanical processes of inducing the residual stresses into the torsion bar are used: the presetting of the torsion bar and the deep rolling of the torsion bar. The process of presetting the torsion bar is carried out by twisting the torsion bar to the desired angle and releasing it to the new residual angle position. With controlled overstraining, favorable residual shear stresses are induced into the torsion bar, so the material is strain hardened and the yield point of the material is shifted and increased in the stress and strain space. The objective of the deep rolling process is to introduce compressive residual stresses into near-surface regions in order to increase the fatigue strength of the torsion bar. These two processes influence each other. The final level of residual stresses depends on the production sequence of these two processes and the production parameters of each process. The correct production sequence of these two operations and distribution of beneficial residual stress was simulated using the finite element (FE) method. To validate this model, the predicted surface residual stresses were compared by the X-ray diffraction (XRD) measurements of residual stresses.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 13930523The knowledge about the diffuse axonal injury (DAI) as a clinicopathological entity has matured in the last 30 years. It has been defined clinically (immediate and prolonged unconsciousness leading to death or severe disability) and pathologically (the triad of DAI specific changes). In terms of its biomechanics, DAI is occurring as a result of acceleration forces of longer duration and has been fully reproduced experimentally.In the process of diagnosing DAI, the performance of a complete forensic neuropathological examination is essential and the immunohistochemistry method using antibodies against beta-amyloid precursor protein (beta-APP) has been proved to be highly sensitive and specific, selectively targeting the damaged axons.In this review, we are pointing to the significant characteristics of DAI as a distinct clinicopathological entity that can cause severe impairment of the brain function, and in the forensic medicine setting, it can be found as the concrete cause of death. We are discussing not only its pathological feature, its mechanism of occurrence, and the events on a cellular level but also the dilemmas about DAI that still exist in science: (1) regarding the strict criteria for its diagnosis and (2) regarding its biomechanical significance, which can be of a big medicolegal importance.

COBISS.SI-ID: 32264921In-wheel motors offer a promising solution for novel drivetrain architectures that could penetrate into the automotive industry by locating the drive where it is required, directly inside the wheels. As obtainable literature mainly deals with optimization of electromagnetic active parts, the mechanical design of electromagnetically passive parts that indirectly influence motor performance should also be reviewed and characterized for its effect on performance. The following study uniquely evaluates the impact of mechanical design and its dimensional variations to air-gap consistency between on rotor glued magnets and on stator fitted winding, for the most commonly used layout of an in-wheel motor. To meet the optimal performance of an in-wheel motor, the mechanical design requires optimization of housing elements, thermal management, geometrical and a dimensional tolerance check, and proper hub bearing selection to assure consistent electromagnetic properties. This article covers the correlation between desired electromagnetic parameters and required geometrical limitations for ensuring functionality and high performance operation. Major mechanical contributors have been analyzed with analytical calculations, numerical simulations, and verified with different sets of measurements. The relative change of motor physical air-gap size, between the stator and rotor was correlated with electromagnetic flux density.
F.06 Development of a new product
COBISS.SI-ID: 15295259The book provides a detailed overview of theoretical basics and established practices in the production of technical documentation in accordance with the latest ISO standards and with emphasis on technical drawing in mechanical engineering. The book first presents the basis of production, handling and manipulation of technical documentation (basic drawing rules, tools, drawing media, types and forms of drawings, reproduction and storage etc.). The following chapters discuss drawing rules and special features (simplifications) of drawing and dimensioning. Also presented are different methods of prescribing requirements on dimensional and geometrical accuracy of objects (deviations, tolerances, ISO fits and tolerances, geometrical tolerances) in regard to surface characteristics (roughness) and object edges. Also included is a systematic overview of special features of presenting typical (standard) machine forms, elements, assemblies and structures as well as creating schematic drawings of devices, installations and processes. Basic rules on the labelling of typical technical materials, thermal treatments and metal coatings are provided. The book also includes an overview of the SIST ISO standards applicable in the field of technical documentation.
