ABSTRACT:
A pad (22) for isolating a weight (4) from vibration of a resonant beam (8) in a resonant beam support system (6) for dissipating heat. The pad is constructed of a rubberlike material having ridges (58) and grooves (60). The ridges and grooves include a trapezoidal configuration which yields an increasing resistance to compression, i.e., spring rate, with increasing deflection. Altering the configuration of the ridges and grooves permits variation in spring rate. The pads may be constructed of standard truck tire recap tread and arranged in a square configuration. Water is injected between the pads and grooves through inlets (50, 52) to cool the pads. An aluminum plate (48) is mounted between first and second layers (40, 41) of tire recap tread to increase heat dissipation.
