Development of an Accelerated Degradation Testbed for Integrated Vibration Monitoring and Online Oil Analysis of Vehicle Differential Bearings
This project, sponsored by the Office of Naval Research, integrates oil and vibration analysis to develop a more complete diagnostic and prognostic model for monitoring bearing degradation and performance while inside a vehicle's differential. The results of this project could be used to optimize repair schedules and minimize the risk of catastrophic failure of machine components for military personnel during a mission through condition-based maintenance. Each test bearing is first introduced with an outer race fault. The fault's degradation is then accelerated by running the bearing under overloaded conditions in the boundary lubrication regime. Accumulated damage to the bearing is characterized in a clean, low-noise environment before being implemented into the differential for in-situ testing. Dynamic characterization of the designed test machines were performed by long runs spanning multiple hours under rated conditions to determine any wear-in effects and ramp-up tests to distinguish order-based bearing frequencies and structural resonances. Modal analyses were performed on the static system to provide additional evidence of structural resonances within the machines. This paper will discuss the design challenges and solutions for creating a test bed to monitor bearings in accelerated-degradation conditions and in noisy environments, such as the differential. Results of run-to-failure data and analysis will also be presented.

Introduction to Oil Debris Monitoring
An introduction to Oil Debris analysis as a diagnostic tool in the health monitoring of critical plant and machinery.
From simple devices to systems compatible with on board health and usage monitoring systems, the application of traditional early failure detection by magnetic plugs is explained along with the evolution to systems offering prognostic potential.

The presentation is aimed at those new or unfamiliar with the benefits of Oil Debris analysis and those who may not include it as their primary technique in preparation for a new career move or to gain qualifications in Condition Monitoring, as well as those exposed to the technique wanting to bring their knowledge up to date.

Reliability Centered Lubrication: Managing the Lifeblood of Machinery
Reliability Centered Lubrication (RCL) is an approach to lubrication focused on designing a program for lubrication and oil analysis considering operational conditions, best practices, and modifications required to both machine and facility. Implementation of an RCL program is carried out utilizing an RCL Design Process, Implementation, and Sustainability. A current state analysis is an excellent starting point, comparing one's own facility to best practices. Understanding equipment needs including engineering calculations and operating conditions for lubrications amounts and frequencies. Putting a lubrication program in place includes implementation of sustainable lubrication routes that add value, coupled with lubrication storage best practices. Finally, sustainment of the lubrication program is founded with lubrication metrics and KPIs that guide continuous improvement.
This presentation provides an introduction to Reliability Centered Lubrication including a case study and tips for getting started.

Advances in Comprehensive Fluid Analysis
We describe advances in comprehensive forward deployed fluid analysis based on fluid condition assessment with FluidScan® and contaminant and wear debris analysis with the LaserNet Fines® optical particle analyzer. The combined technologies provide comprehensive analysis of fluid condition and machinery health, and are implementable either as a forward-deployed portable instrument or a continuous, autonomous online monitor. The combined technologies provide comprehensive immediate on-the spot actionable information at the operational level about the current condition of platforms and machinery, readiness for deployment or usage, and advanced warning about impending failures or need for specific maintenance. A forward deployed portable instrument is of value for use in monitoring fleets of vehicles or platforms with a single instrument through bottle sampling, while an online monitor is of value in providing continual assessment of the condition of critical, high-value equipment where serious faults can develop between bottle sample intervals, and support reduced manpower or workload environments.

Previously we have described the combination of LaserNet Fines® and FluidScan® into a single portable unit capable of analyzing lubricating and hydraulic oils1. Our current efforts involve extending the capability of the portable instrument to fuel analysis. We have developed fuel analysis algorithms for identifying if unknown fluid is a fuel, distinguishing among multiple types of aviation and diesel fuels and gasoline, and calculating multiple physical properties depending on fuel type. In the current effort, we are incorporating this capability into the portable analyzer utilizing an extended range mid-IR spectrometer that can analyze lube oil, hydraulic oil and fuel in a single instrument.
Advances in the online monitor include extending the capabilities of the online LaserNet Fines® particle monitor to include gearbox oils, as well as, hydraulic and engine lube oil and to combine it with an online FluidScan® monitor. We will describe results with both the portable and online units for analysis of engines and transmission.
