1. Multidisciplinary Capstone Design:
Loading, Measurement, Control, and Test of a
Journal Bearing Test Platform
Problem
The test rig we were presented with needs to be able to measure multiple quantities (oil flow, vibration, eccentricity, and displacement).
The rig suffers from backlash in the EMA load profile.

Customer Requirements
Morphological charts were used in order to assist brainstorming by means of organizing visual concept ideas.
Key requirements the customer expects to be produced as an end result of the project.
Concept Selection
Pugh Charts were used to assist in comparing overall effectiveness of ideas based off of aspects such as cost, feasibility and chance of success.
Functional Decomposition
Steps in order to achieve the customer and engineering requirements.
Spring/Preloading System
Initial concept for eliminating the backlash in the system.
Risk Assessment
Measures the importance of risks associated with design based on likelihood and severity. Priority was given to the most important risks.
System Architecture
EMA Joint Redesign
An easy to follow guide on how the subsystems of the rig interact with each other.
Simplified previous joint design to two mating faces.
Oil Flow Results
Accelerometer Calibration
Can the oil flow rate be improved by reducing the journal shaft diameter?
Can the accelerometers accurately measure the vibration on the test rig?
