The contents of the paper point out the necessity of combining the theoretical and experimental approaches in the investigation of tire load in vehicles. The models are planar and they model the cross-section of the tyre enabling the consideration of the bottom load and the internal pressure in the tyre, as well as the influence of the lateral force. The paper presents the findings, the formulations necessary for solving the task obtained in the experimental model tests and serving as a basis for comparison with the results obtained from purely theoretical approaches, e.g. by the method of finite elements, with identical load conditions.

For observatory of vibrations of aluminum rectangular plate was used two different methods: mathematical and experimental. Experimental part was done by holograhpy speckle interferometry (HSI). This method - HSI - is very suitable for non-destructive observatory several types of materials - in our experiment is it aluminum rectangular plate. Results of this method - vibration modes - are applicable especially in designing of various structures. Results of the mathematical modeling are suitable for verifing and comparison with results from HSI method - they are very comparisonable. In our mathematical modeling program MARC was used with help of the FEM.

All rotating machinery generates vibration, the analysis of which renders valuable information about the condition of the machines. This article describes the type of vibration signals to be expected for faults in typical elements and the analysis techniques to be used for early detection. Furthermore, diagnostic methods are described witch permit estimation of the remaining life of an element once a fault has been detected.
