Design of experiments for studying the Effect of Nano-Additives Lubricant on Vibration Signals of Defective Rolling Element Bearings

Project Overview

Our project consists of two main parts. Firstly, add modifications to a previously built test rig such as: a hydraulic loading system, bearing housing, oil tank, selection of new bearings, and suspend the nanoparticles in the lubricant using ultrasonic. Secondly, conduct experiments to test healthy bearings and defected bearings when lubricated with a nanoadditive oil based lubricant. We are going to vary different characteristics of the nanolubricant such as concentration and particle size to reach a number of conclusions (i.e. vibration signal, friction, wear, and thermal properties).

Project Objectives

The four main objectives of this project are:
  • Test the vibration signature of rolling element bearings lubricated with different concentrations of nanoadditives oil based lubricant, operating under different loads, and at various speeds.
  • Provide a thorough experimental investigation into the effect of different lubricants and nanoparticle additives on the characteristics of the vibration signal and the effect of detecting the presence of the defect and the amount of masking provided.
  • Simulate the effect of nanomaterial additives on the vibration signature. This aims at provided a much needed initial and sound model into the attachments of the nanomaterial particles to the defective area and will form a base for further research into this area.
  • Enrich the body of research with new much needed knowledge into this new twenty first century science.
