Abstract
Representation of elastomers for use in modeling of linear systems requires great care in the acquisition of test data. Current industry-standard test techniques are not adequate for quantitative description of elastomers subjected to small amplitude sinusoidal excitation. Equally important to accurate dynamic testing of elastomers is parameterization of the test data for use in modeling of systems.
The paper discusses testing and parameterization techniques used to describe elastomers for use in a linear, low-frequency vibration model of an automobile. Accuracy requirements of test instrumentation, selection of suitable linear elastomer models, and interpolating functions (used for equivalent linearization and ambient condition corrections) are discussed in some detail.
