Linear guiding systems are used in machines for relative translational motion of components, especially for handling devices, which are the basis of production lines. In these operating conditions, the linear guiding systems are dynamically loaded. Dynamical influences may lead to the decrease and damage of bearings. The aim of this paper was to calculate dynamical influences of a mass inertia on linear guiding systems. This issue was solved by a numerical calculation of differential motion equations in 2D. The motion was calculated on an example of a handling machine for welding car bodies. The result is a percentage representation of the dynamic forces on the total load of the linear guiding systems. The result shows the percentage representation in the solved case as more than 10%.

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 lockin method which were compared with the results from the experiment.
