Abstract
A machine includes a frame and an operator cab supported by the frame. One or more passive mounts and one or more controllable mounts operatively connect the operator cab to the frame. The one or more controllable mounts include a housing, a pin mounted within the housing, a rheological fluid within the housing, and coils positioned relative to the housing to generate a field through the rheological fluid. An electronic control unit operatively associated with the coils and adapted to change a level of current applied to the coils to adjust an apparent viscosity of the rheological fluid to actively change the damping characteristics of the one or more controllable mounts.
