Discovering and Eliminating Resonances
The course material helps to understand the phenomenon of resonance through a detailed explanation of the physical basics. With knowledge of the theory, methods for detecting and avoiding resonances become easily understandable.
Deepening of knowledge is guaranteed by presenting examples taken from practice - different from the usual ones - and by numerous demonstrations ranging from coast-down measurements to impulse hammer tests.
- Small-group (max. 20 participants) one-day course
- Detailed (approx. 30 pages, color) Hungarian-language study material
- Lecture projected with a computer projector (½ day)
- Hands-on training (with training test pads and our company's full range of instruments)
