Workshop Description:
This 3-day practical workshop provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined.
The acquisition and processing of signals is reviewed followed by a discussion of machinery fault diagnosis using vibration analysis and rectifying the unidentified faults. The latest approaches and equipment used together with current research techniques in vibration analysis are also highlighted in the workshop.
The training component of the workshop will be in preparation to those who plan to take the Level 1 Vibration Analyst Certification exam. The Vibration Analyst Certification uses body of knowledge compliant with ISO 18436-2 and is enhanced by a job-task analysis conducted by the accredited certifying body.
ISO 18436-2 specifies the general requirements for vibration analysis personnel who perform machinery condition monitoring and diagnostics of machine. Certification to this standard will provide recognition of the qualification and competence of individuals to perform machinery vibration measurements and analysis using portable and permanently installed sensors and equipment. ISO 18436-2:2003 covers certification program that is based on the technical areas discussed herein.
