Abstract
A powertrain mounting system for a vehicle powertrain includes a first powertrain mount that exhibits a first gradual rate of change of static stiffness when under load. The mounting system also includes a second powertrain mount that exhibits a second gradual rate of change of static stiffness when under load. The first gradual rate of change of static stiffness is related to the second gradual rate of change of static stiffness by a static equilibrium torque balance equation of respective displacements at the first and the second powertrain mounts. The static equilibrium torque balance equation is based in part on a spatial arrangement of the first and the second powertrain mounts relative to the powertrain. A method of designing the powertrain mounting system determines the first and second gradual rates of change of static stiffness under load to achieve efficient energy management.
