Analýza závislosti vibrací kardanové hřídele na její zástavbové délce

Abstract

This thesis deals with vibration analyses, which are generated during rotation of cardan shaft with two joints. First part of this thesis describes basic cardan shaft cinematics. In this part I specify analyses of cinematic dependences of cardan shaft. Analytical calculations are verified by FEM analysis (Final Element Method). After theoretical part follows FEM analysis which is looking for dependence length of cardan shaft on his own frequency. The effects of the gearbox suspension are being investigated too. This thesis also contains vibration analysis, which was obtained in real measurement on vehicle. In the end of this thesis is performed experimental modal analysis.
