Machines and structures in plants have their own natural frequencies. However, the operating conditions usually do not match these natural frequencies, so the machine or structure does not resonate. If they continue to operate, they may enter a resonance condition as their stiffness changes due to looseness, friction, etc. In fact, if we examine the causes of defect conditions, about 50% are due to resonance.
Understanding how to detect, analyze, and correct resonance is very important. This training provides understanding and presentation of how to approach problem-solving by measuring and analyzing natural frequencies and determining how the measurement object behaves at that frequency.
