Abstract

This research article describes the design and construction of a prototype mechanism for low frequency vibration isolation used to study and develop the method to suppress the low frequency vibration from floor which will disturb the experimental system. A prototype mechanism is designed and constructed based on a mass-spring system using three air springs as vibration suspension system then studies the behavior of vibration pass through the system and ratio of suspension pass through the system when different air pressure is supplied to the air springs. The experimental results show that the prototype mechanism for vibration isolation can suppress the low frequency vibration, which frequency is in a range of 1-5 Hz, with averaged ratio of 85% when the supplied air pressure to air springs is in a range of 2 - 4 bar.
