Tension-based Multi-stable Compliant Rolling-contact Elements

Peter A. Halverson, Larry L. Howell, Spencer P. Magleby

ABSTRACT: This paper presents models for a tension-based, multistable, large displacement, compliant rolling-contact element (CORE). The models are capable of determining stress, strain, and retaining forces and are derived using a strainenergy approach. Models are compared to empirical results and the utility of these models is demonstrated in a case study. The case study demonstrates a device with multiple stable equilibrium positions and tests the fatigue properties of tension-stable CORE.
