Filled Rubber Isolator’s Constitutive Model and Application to Vehicle Multi-Body System Simulation: A Literature Review
Abstract:
Rubber elements present highly nonlinear mechanical properties affected by
frequency and amplitude of excitation, prestrain and temperature, etc. Finite
element (FE) models and lumped parameter models can be distinguished in the
development of constitutive models of rubbers. Based on the concept of overlay
model, different kinds of viscoelastic, or frequency-dependent models, and
elastoplastic/friction, or amplitude-dependent models, are compared in terms of
their modelling approach, parameters identification process and applications.
Prestrain-dependent models and temperature-dependent thermo-mechanical models
are also reviewed, including some special models which are not based on the
concept of the overlay model. Experimental and computational studies of
cylindrical bushings subjected to coupled deformation modes are analyzed and
discussed. It is the hope that this literature review work can help clarify and
guide the future research and development direction about rubber constitutive
modelling.
