Opis:
This paper presents dynamic and stress analysis of a virtual prototype (VP) of a lock mechanism, which would lead to verification of its functionality in terms of kinematic, dynamic and strength parameters. The proposed modifications of input parameters of the technical equipment addressed were verified using the software environment of MSC. ADAMS and FEM software ANSYS Workbench.

Opis:
This article dealt with the comparison of results obtained from an experiment and from the numerical thermal FEM analysis. Sample with defects were printed on a 3D printer. A thermal wave from the halogen lamp to excite the front surface of the sample was used in the next step and the response was measured by a thermal camera. After processing the data in the software DisplayIMG, a phase image was created representing the 2D image of the material at a certain depth under the surface of the model. Lock-in method was applied to the results from the numerical thermal FEM analysis and the phase image was created. The programs code were created in MATLAB for a 4 points, multiple points and differential lock-in method which were compared with the results from the experiment.

Opis:
This article is focused on the height adjustment of a front car seat. The goal was to design seat movement in pure vertical direction. The article begins with a theoretical introduction, in which the functions and parts of car seats were described. The next part contains possible schematic designs of a mechanism, as well as the reasons for possible changes of the contemporary mechanisms. Afterwards, some functional parameters of the chosen schematically-designed mechanism were calculated, the results could then be used for further calculations needed for the creation of a three-dimensional model of the mechanism. The article deals mainly with the theoretical principles, and there are many further possibilities for development within the subject.

Opis:
In-situ study of deformation behaviour and mechanisms occurring during early stages of deformation is of a great practical importance. Low stacking fault energy materials, as is the case of AISI 304L, show non-linear deformation characteristics way below the bulk yield point. Shockley partial dislocations, formation of stacking faults respectively, resulting in creation of shear bands and ε-martensite transformation are the mechanisms occurring in the low strains in the studied steel. Acoustic emission and infrared thermography have been used in this study to investigate the deformation kinetics at the low strain stages of slow strain rate tensile tests. Acoustic emission cumulative energy together with the tracking of specimen maximum temperature have been found to be very useful in-situ techniques both supplementing each other in the sense of the sensitivity to different mechanisms. Mechanical, acoustic emission and infrared thermography results are discussed in detail with respect to potential occurred mechanism.
