GMW14738 3rd Edition, October 2018 Master Test Procedure for Determination of Dynamic Stiffness and Loss Angle of Elastomeric Components
More info
Description / Abstract:
Introduction
Note: Nothing in this standard supercedes applicable laws and regulations.
Note: In the event of conflict between the English and domestic language, the English language shall take precedence.
Purpose.
The purpose of this procedure is to determine the dynamic stiffness and loss angle (viscoelastic properties) of elastomeric components used in vehicles when subjected to forced sinusoidal oscillations in the temperature range of -50 °C to +150 °C.
Applicability.
This procedure is appropriate for the evaluation of all elastomeric components.
Remarks.
The dynamic stiffness and loss angle characteristics of elastomeric components in the vehicle chassis are important contributors to vehicle noise and vibration isolation as well as ride and handling performance.
