| Abstract [eng] |
This final work presents the measurements and results about vibrations at the stand, which consists of rotary system and foundation. The foundation is one of the most important parts of the rotary system, which ensures reliable work. Designers often makes a lot of mistakes in designing the foundations, which are completely not suitable for the rotary system, misjudge the foundation‘s natural frequency of the vibrations, so there are such rotary systems, which functions close to resonance. This paper has investigated several types of foundations. The foundation is analysed together with the rotary system applying a method of combinative research: numerical modeling (BEM) and the analysis of vibrations‘ signals. Based on the research results, it tries to determine the impact of the lack of foundation rigidity to the rotary systems‘ dynamic and stability. |
