Jáuregui Correa, Leonardo Urbiola Soto, Carlos Díaz Díaz, Fernando Aboites Dávila CIATEQ A.C. Aguascalientes, Ags. jcjaur@ciateq.mx ABSTRACT A multidimensional finite element model of a viscoelastic sliding bearing is presented.
The model consisted on two independent matrices, one represents the stiffness behavior and the other represents a damping matrix.
These matrices are independent from each other since the viscoelastic material properties are assumed to be a Kelvin type material.
Kelvin type materials are approximated as a linear combination of an elastic modulus and a viscous coefficient.
This simple model describes accurately almost any rubber found in several machine components. The model combines the linearity of the Kelvin type material plus the finite element interpolation scheme.
Thus, the advantages of the finite element method can be applied to any geometry. In order to obtain Kelvin´s coefficients, a test rig was built.
Material properties were experimentally determined and the model was validated.
Afterwards, a discretized...
