Control system for reducing powertrain induced vibrations

摘要

A vibration control system is disclosed for a machine having a powertrain secured by a mounting system. The control system may include a first sensor, a second sensor, a vibration inducing device, and a controller. The first sensor may be configured to generate a first signal indicative of a parameter of a work cycle of the machine, and the second sensor may be configured to generate a second signal indicative of vibrations induced by the powertrain. The controller may be in communication with the first sensor, the second sensor, and the vibration inducing device. The controller may be configured to classify a current operation of the machine as one of a plurality of predetermined segments of a work cycle based on the first signal, to predict a vibration profile that will be generated by the machine during a future segment of the work cycle, to tune a listening window based on the vibration profile, and to generate a command wave directed to the vibration inducing device to generate canceling vibrations during the future segments based on the second signal received within the listening window.
