ABSTRACT:
A tunable powertrain mount for use in an automobile has a shear disc suspension coupled between a frame rail and a cross member supporting the powertrain. The shear disc suspension has two elastomer discs interleaved between three support plates. The shear disc suspension is tunable as a function, at each deformation stage, of load, displacement, stiffness and frequency, and as a function of area, support mass, shear modules of the elastomer and maximum shear strain.
