Hand Arm Vibrations (HAV) an acute problem with the human operated tools. The prolonged use of such vibrating instrument may cause serious injuries to the sensitive organs of human body. Tuned Vibration Absorbers (TVA) are the secondary device attached to the primary system to control its vibrations. Here an attempt has been made to design and simulate the Tuned vibration absorber for a Hand blender. The natural frequencies are obtained by the Modal analysis in ANSYS ® and the results are simulated in MATLAB®. The response of the hand blender is determined experimentally before attaching and after attaching TVA, a 27% reduction in Displacement RMS is obtained.
