The present invention refers to a washing machine for washing laundry, comprising a body with a casing (1) and a front wall (2) having an access opening (3) for loading/unloading laundry to be washed, wherein a plurality of vertically adjustable supports (13) are connected to the lower section of the casing (1) and the front wall (2) which is intended for mounting the washing machine on a surface. It is provided for according to the present invention, that at least a horizontal fold (4,5) of the casing (1) or of the front wall (2) is at least partially and/or at least piecewise continuously formed with a reinforcing elevation (16) extending in the longitudinal direction of the fold (4, 5).

COBISS.SI-ID: 15518747This thesis presents the numerical modelling of dynamical systems with the Component-Mode Synthesis techniques. They are used to model the system response of complex structures with variable contact conditions during operation. A comparison of four classical Component-Mode Synthesis techniques is presented. The formulation divides the complex structure into reduced substructures and enables efficient identification of structural modifications on the system response. The results, in comparison with an experiment, demonstrate the efficiency as well as the physical consistency of the used techniques. The Component-Mode Synthesis techniques are used together with the developed mixed-contact formulation to model the system response. New explicit event-driven integration schemes are presented. The developed integration process defines three possible contact states, that require the definitions of the reduced-system matrices as well as to update the initial conditions. The efficiency of the methods is demonstrated on a real structure, which also serves for the validation of the developed numerical formulation.

COBISS.SI-ID: 292420096This research presents an overview of the necessary theory and standards for the research of the biodynamic response of a human body and its' vibroisolation protection. In the first part, two different biodynamic measuring devices are developed. The first device is designed in the shape of a handle and separately and concurrently measures the palm and finger responses to vibration excitation. The device enables triaxial measurements and can also be used for antivibration gloves testing. The second device was developed for single finger and finger parts biodynamic measurements. Based on the measured results a finger dynamic model is developed and also validated. The analytical finger model is designed as a system of rigid bodies and the material properties of the model were identified from the experimental data. The developed model serves as a simulator of the finger response to excitation and with added vibroisolation elements helps in the development and testing of antivibration protection of the human hands. At the end of this work, the upgraded analytical finger model is used to research different vibroisolation materials and some antivibration protection proposals are listed.

COBISS.SI-ID: 15765019This research presents the approach to modeling of multibody systems assambled of rigid and exible bodies and interconnected with adequate kinematic constraints. With a goal to evaluate the dynamic response a kinematic constraint, pin-slot clearance joint, is developed. The developed pin-slot clearance joint is numerically and experimentaly researched and then used when modeling a multibody system assmabled of rigid and exible bodies. The dynamical system in focus is based on the real engineering application and used to study the effect of pre-stress on dynamical response.

COBISS.SI-ID: 15748635This research compares spatial damping identification methods, both theoretically and experimentally. In contrast to the commonly used damping methods (modal, proportional) the spatial damping information improves structural models with a known location of the damping sources. The real case robustness of full FRF matrix and local equation of motion methods were tested against: modal and spatial incompleteness, differences in viscous and hysteretic damping models and the effect of damping treatments. To obtain accurate results, a careful analysis of measurements in terms of reciprocity in the raw measurements, and in terms of how to preserve symmetry has to be done. It was found that full FRF matrix needs to be symmetrisized due to small deviations in reciprocity before the damping identification. Full frequency response function (FRF) matrix methods (e.g.: Lee-Kim) can identify the spatial damping if spatial and modal incompleteness are carefully evaluated, but the measurement effort increases with second order and, consequently, the size of the FRF matrix.
