Abstract:
A work machine controlled by an operator and acting upon a load through a plurality of work cycles, comprising:a frame;a plurality of ground engaging devices supporting the frame;an operator compartment supported by the ground engaging devices;an implement having a linkage for connecting the implement to the frame;an engine coupled to the ground engaging devices; anda stress measurement control system, including:a strain gauge sensor assembly mounted to at least one of the frame and implement and providing a stress signal having a stress signal value indicative of a stress acting upon at least one of the frame and implement;a memory storing at least one stress signal value and at least one pre-determined stress limit value;an electronic controller associated with the memory and receiving the at least one stress signal and the at least one pre-determined stress limit value, determining whether the stress signal value is greater than the pre-determined stress limit value and responsively providing an associated message; andan operator interface receiving the associated message and providing the associated message to the operator in the operator compartment.
