3. ngineering change in place to replace the monitoring system but the mod was abandoned Due to obsolescence and reliability issues the VL vibration monitoring system has been defeated Data is collected weekly or bi weekly by Maintenance technicians Initial Project Requirements e g weight size etc This project will evaluate the vibration monitoring system to identify parts that cannot withstand the environment and design a new system which will be able to withstand the environment To accomplish this the following must be accomplished Purchase the current system from the PLC center Duke Energy will assist with this Identify all of the components in the system and create a Bill of Materials Identify components that are obsolete i e no longer manufactured Identify which components cannot withstand the environment in which the system is installed through research testing and analysis we UNC CHARLOTTE The WILLIAM STATES LEE COLLEGE of ENGINEERING e Redesign the system and develop a prototype e Develop a test rig and Test the prototype to verify that it correctly monitors the required vibration frequencies and can withstand the environment in which it will be installed Expected Deliverables Results The deliverables will include a prototype with a user manual complete with operating and maintenance instructions and all design drawings A complete report of the analysis findings and results will provided Personnel Check
