Audible stiffness of a preloaded vibration isolator at different temperatures
2003 (English)In: Proceedings of the Tenth International Congress on Sound and Vibration, Stockholm, 2003, 853-860 p.Conference paper (Other academic)
The results of a temperature and preload dependent dynamic stiffness model of a cylindrical vibration isolator are presented throughout the whole audible frequency range. The stiffness is found to depend strongly on frequency, preload and temperature. A nearly incompressible, thermo-rheologically simple material model is adopted, being elastic in dilatation while displaying viscoelasticity in deviation. The latter exhibits a time-strain separable relaxation tensor with a single Mittag-Leffler function embodying its time dependence. The weak formulations corresponding to the audible stiffness problem are solved by an updated Lagrangian nonlinear finite element procedure.
