METHOD AND A DEVICE FOR REDUCING VIBRATIONS IN A WORKING MACHINE
First Claim
1. A method for reducing vibrations in a working machine, the working machine comprising a hydraulic system with a hydraulic machine for providing hydraulic fluid to at least one working function, the hydraulic machine being driven by a drive source having a variable speed of rotation, comprisingidentifying a resonance frequency for the working machine, andcontrolling the drive source so as to counteract waves with the resonance frequency.

Abstract
A method for reducing vibrations in a working machine is provided. The working machine includes a hydraulic system with a hydraulic machine for providing hydraulic fluid to at least one working function. The hydraulic machine is driven by a drive source haying a variable speed of rotation. The method includes identifying a resonance frequency for the working machine, and controlling the drive source so as to counteract waves with the resonance frequency.
