Project Description
Project Background:
Eaton Corporation designs luminaires for industrial applications where they are exposed to extreme conditions. Many tests are run on the luminaires, including a 35 hour vibration test. Eaton currently owns an apparatus to perform this task, though it was designed and built decades ago. An updated apparatus is required to ensure accuracy and safety.
Problem Statement:
Design an updated vibration test apparatus capable of vibrating luminaires at 2000 RPM for 35 hours with a displacement of 1/32”. Updated system should include better lubrication containment, adjustable displacement, single technician set-up, and more accurate adjustment of frequency.
Objectives/Scope:
  1. Increase accuracy and adjustability of apparatus.
  2. Increase ease of set-up
  3. Increase apparatus safety
Deliverables
  1. Provide two preliminary design concepts for the customer to select from.
  2. Develop a final design based on customer input which includes:
  • Final vibration mechanism
  • Test frame to support vibration mechanism and vertical conduit of luminaire with luminaire attached.
  • Final design of complete test apparatus frame
  • Complete engineering drawings
Expected Project Benefits:
  1. Increase in accuracy of tests performed on luminaires
  2. Improved ease of use

Core Team Members:
  • Walter Bergstrom
  • Sean Coots

  • Mark Ellison

Strategy & Approach
Assumptions & Constraints:
  1. Apparatus must be accurate with the ability for adjustment
  2. Apparatus must be able to be set up by a single technician easily
  3. Apparatus must fit into current vibration test room
  4. Apparatus must be robust enough to last at least as long as the current apparatus
Issues & Risks:
  1. Since this is a redesign of a current system, it may be difficult to “think outside the box”
  2. Parts/materials not order/delivered on time will delay prototype construction
  3. Different schedules could make it hard to meet as a group
