Coupled analysis of heat production in cyclically loaded viscoelastic rubber components

The widespread use of elastomeric components for the suppression of noise a nd vibration levels in modern machinery and transportation vehicles has cre ated a demand for analytical techniques to predict component response under static and vibratory toads. Component response characteristics such as sta tic force-deflection behaviour and dynamic stiffness at various input frequ encies and preloads are important design considerations utilized in the con struction and selection of mounts and bushings, A method to calculate the t emperature change in a component with a non-linear pre-stress state subject ed to small amplitude vibrations will be presented. Heat production is caus ed by energy dissipation in viscoelastic materials.
