Advanced Air Isolation System for Precision Devices

Precision devices such as coordinate measuring machines (CMMs), microscopes, MRI machines, and other test/scanning equipment are highly sensitive to vibration, caused by other nearby equipment or even human activities. The adverse effects of vibration on such devices should be mitigated by properly isolating them from the surrounding via elastically mounting them on their support concrete […]

Active Stiffness Control of Air-Mounted Systems

Air mounts, with their attractive attribute of being able to provide the most softness of all mounts of comparable size, have been gaining popularity and widespread use. The drawback of soft mounting is occasional excessive motion of the mounted machine in response to abrupt, impulse-like disturbances (such as starting up or shutting down an engine). […]

Active Damping of Air-Mounted Systems

Compared to elastomeric (rubber) and coil spring mounts, air mounts with their very low stiffness, provide the highest degree of low-frequency vibration isolation. Lack of damping in air mounts, although lowers the noise and vibration transmission of the mounted machine, will deteriorate its shock isolation attributes. This is mainly due to the creation of a […]

Computer Controlled Air Isolation System

An Advanced Mounting System for Diesel Generators Onboard Luxury Watercrafts An ideal mounting system for yacht diesel generators should be 1. Soft, while the yacht is not moving, i.e., the propulsion engines are off and calm and quiet are expected. This will prevent the transmission of vibration and noise, through the hull, to the living […]

Structure-borne Transformer Noise Reduction by Air Isolation

Transformers transmit noise partly through the air (airborne noise). In addition to the airborne noise, transformers transmit vibration through the structure of the support structure, where the transformer is installed on, to the neighboring spaces causing structure-borne noise. The airborne part of the transformer noise is normally abated by enclosing the transformer in a soundproof […]

Air Isolation of a Diesel Generator

To lower the vibration transmitted from a 170 KVA diesel generators onboard a super yacht, to the hull (and thus the living quarters) of the boat, it was decided to soft mount that diesel-generator by changing its conventional (elastomeric) mounts to air mounts. The attachment of the exhaust pipe to the engine, as well as […]
