Goals
 Design a simple push pull actuator
using basic mechanical components.
 Low cost
 Shape the force feedback (output)
 Model proof of concept using nonlinear
Finite Element Analysis
Concept

Predicted calibration curve
CLOSE GAP
INITIAL LINEAR RUBBER RESPONSE
RUBBER HYPERELESTIC RESPONSE
Analysis method
 Solidworks Simulation 2015
 Nonlinear static analysis
– Nonlinear material properties using
Mooney-Rivlin constants
– Buckling geometric nonlinearity
 Solution is calculated 50 times at
equally spaced steps
Torsional input mode
Conclusion
 This actuator response acts
approximately as a digital state flip or
a switch.
 This design could be miniaturized.
