Machinery Failure, Vibration & Predictive Maintenance

Introduction:

Machines deteriorate as they get older so we can expect a certain amount of performance falloff and general deterioration of the machine. If we understand the failure mechanisms that are in place we can identify which parameters best indicate the deterioration of the machine.

Failure analysis and Predictive Maintenance techniques, including vibration analysis, are discussed in the training course to optimize the maintenance engineering effort while maximizing production. Other techniques that will be addressed include infrared thermography, passive ultrasonics, tribology, and performance monitoring
