Course description and aims

【Course description】
The course teaches Fourier analysis, self/mutual correlation and criteria as the basis of vibration/sound analysis and diagnosis, vibration measurement of a rotating machine, sound measurement.


【Aims】
Students learn the basis of vibration measurement and how to detect unusual vibration/sound and diagnose it.

Student learning outcomes

By the end of the course, students will be able to understand theoretical basis of Fourier transform and application for measurement and analysis.

Keywords

Fourier transform, Spectrum, Vibration of rotating body, Vibration diagnosis, Sound measurement

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Do the exercises each time and submit a homework by the next lecture.
