Abstract

An innovative concept for active ride control reduces machine oscillations based on frequency identification.

Earthmoving machines are typically involved in handling heavy loads, and for this reason they often do not incorporate wheel suspensions. Because of this, vibrations caused by driving on uneven grounds are transmitted to the machine arms and chassis. Hydraulic fluid's ability to store potential energy introduces additional oscillation tendencies to the machine.

Oscillations can cause several negative effects, including creating instabilities at the load. This is particularly important for earthmoving machines, as their primary purpose is typically transporting a load. When oscillations cause material to fall from the bucket, this reduces the working efficiency of the machine. Operator discomfort is another problem caused by low-frequency high-amplitude oscillations being transmitted to the operator.
