Question

Can I transfer vibration with hydraulics?

Answer 1

Hydraulic hoses and tubing can be transmitters of fluid-borne vibration inhydraulic hoses and tubing, turning structural components into “speakers.” ... Structure-borne noise starts with vibrationfrom an external source or component, and then transfers directly into the electric motor and structure of a machine.

Answer 2

Proper hydraulic-line configuration can be used to maintain vibration isolation when pumps and electric motors are mounted on isolators.

A proper combination of rigid and flexible conduit can provide a more stable configuration, providing reduced vibration and noise.

Isolation of hydraulic lines and hoses from the application structure (i.e., frame, supports, or panels) offers another opportunity to reduce noise in the design of the machine.

Panels and shields can often act as speakers and amplify relatively low vibration levels into high noise sources.
