In day-to-day life, the concept of rotary machines appears everywhere in diverse engineering applications. In rotating machinery, the safety and performance of the entire system are considered as the significant factors which has to be monitored continuously. As the speed of the motor increases, the amplitude of vibration varies rapidly, and the excitation is due to the elements of rotating structure. There are various parameters that affect the vibration in the rotor during different rotating speed. In this paper, rotor made of mild steel and supporting structure made of cork, synthetic rubber was considered, and these parameters were tested for similar condition with and without magnetorheological fluid damper. This damper is used to reduce the vibration in the shaft due to whirling of shaft at critical speeds. The vibration characteristics of the rotary machinery were studied with change in the base material of the supporting structure. From experimental result, it was observed that the rubber base material reduces vibration much better when compared to cork material. The percentage of reduction in the shaft vibration shows that it is better to use rubber base material with Magnetorheological fluid damper rather than the cork material even though vibration was reduced considerably when both base materials was attached to the setup with MR damper.
