Description
Summary:Some key organizations and programs, either in place or planned, that are concerned with machinery monitoring, diagnostics, prognostics and failure prevention will be identified with the hope of motivating more effective interchange of information on advances in turbomachinery maintenance technology and improving communication links among the key players. Potential sources of unreliability6 include the following: failure to recognize the operating environment and the distribution of applied stresses; inadequate design margin (e.g. inadequate strength); human error (in operation and maintenance); low "extreme values" of strength (e.g. bimodal distribution) caused by material defects, design deficiencies or manufacturing induced faults; poor maintenance and inspection practices and abuse. Reliability Centered Maintenance (RCM) is a concept which applies an analytical methodology or logic to set up specific preventive and predictive maintenance tasks for complex systems.
