The use of equipment and interpretation of test results requires considerable understanding of vibration phenomena as well as analysis and experimental concepts. Consequently, the user of this equipment can be the dominant influence on the quality of test results. This course gives the attendee the basic rules and tools required to make meaningful vibration measurements and to recognize when these measurements may be of questionable quality. In other words, this course helps you to do your job better with more confidence in the outcomes. See Return on Investment Table.
Transducers never lie.
However, they are well known to be careless with the truth as to the phenomenon causing the output signal. Digital Frequency Analyzer Basic processes used in a practical analyzer, why anti-aliasing filters are needed and window functions control analysis filter characteristics, zoom analysis, the dual channel analyzer and the effects of signal noise on measured results. The electromagnetic vibration exciter, armature dynamics, voltage mode and current mode amplifier effects, force drop out at test system resonance when attached to structure under test. Application of Basic Concepts to Vibration Testing Step Relaxation tests, impulse testing, selecting windows for impulse testing, driving a structure with a vibration exciter. Who Should Attend Engineers who are routinely engaged in vibration testing, analysis, and design and would like to expand their knowledge.
