3-DOF SHAKER

• Tom Vose
• Laura Winfield

2
Objective

• Create a 3 DOF mechanism for part alignment using
  a vibrating beam

3
Background Concepts

• Asymmetric oscillation creates directional motion
• Relative acceleration
• and effective gravity

4

• Preliminary Design
• 6.5 inch wide speakers with 3 mm throw
• Linkage lengths of 5 cm
• Original Position of Linkages _at_ 45o
• Undergoes only planar translation and rotation
• 5 accelerometers for position control

5
Current Work

• Created a Matlab program based on preliminary
  system kinematics to deliver workspace
  limitations
• Prototyping with Foam Core
• Testing electronics (i.e. accelerometer,
  amplifier)
• Interfacing electronics with LabView

6
Matlab Workspace
x-y workspace at alpha 1o
Complete alpha-x-y workspace
x-y workspace at alpha -1o
7
Short-term goals

• Explore larger throw speakers to increase usable
  workspace
• Complete Prototype
• Create LabView program for interfacing
  accelerometer with prototype
