Abstract
A machine employing controllable mounts and a method for controlling such mounts based on operator input are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so is the stiffness and damping of the controllable mount. Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback. This can be done through an operator interface that enables an operator to specifically set the current to each mount, or enter other information whereupon a processor of the control system executes the necessary algorithm to provide the operator with the optimum level of feedback.
