BISOPE series 59- Two measurements and methods for vibration evaluation

-------------------------------------------------------------------------------------------------------------

When measuring the vibration of an object (test object, mechanical structure, building, etc.) and trying to quantify and evaluate its size, we are asked that it is difficult because the evaluation unit required by the vibration standard and the output unit output from the vibration sensor are not the same. . For example, according to the management manual provided by the machine manufacturer and construction company for evaluation, it is said to evaluate in terms of displacement. However, if the measurement sensor currently being measured is an acceleration sensor, is it possible to obtain it by converting to displacement (simply integrating twice)? This is about ? What should I do right?

BISOPE series 40- Vibration evaluation grade and notation method (level of vibration state ABCDE)

--------------------------------------------------------------------------------------------------------------------------------------

The person in charge of vibration technology is bound to hear the question, “What is the current vibration state of the object in question (equipment, structure, building, etc.)?” from the manager or the person in charge of other technologies. You can even ask about the results when you have only measured and delivered the data. So always have an answer ready for your question.

Basically, evaluating the state of an object requires comprehensive judgment based on absolute, relative, and mutual standards, so it is not easy to answer at the time. . The evaluation of the state of this absolute standard is mainly divided into good / bad / unacceptable, and the various expressions and standards have been summarized.
