Finite Element Analysis of Viscoelasticity of Test Pieces for Tactile Sensor

In this paper, we present an analysis of the viscoelastic characteristics of a silicone rubber test piece for a tactile sensor using the finite element method. The calculated characteristics of stress relaxation and dynamic viscoelasticity agree well with the experimental values. The results can be used for designing a standard test piece for the evaluation of the measurement accuracy of a tactile sensor.
