Review on Dynamic Vibration Absorber for Handlebar

Motorcycle riders typically experience hand-transmitted vibrations in the hand-arm system from extended exposure to handlebar vibrations, which can cause discomfort, numbness, and shaking. To reduce handlebar vibration, this study investigates the adoption of a Dynamic Vibration Absorption (DVA) system. The DVA effectively reduces vibration at the handlebars by transferring vibration from the primary handle system to a secondary mass. The removal of elastomeric material from the DVA mounting points, the secondary mass's symmetry, and the DVA attachment's direction are some of the variables that affect how well a vibration is absorbed. It was discovered through a series of studies that the motorbike engine is the primary cause of handle vibration and the road's abrasiveness is a secondary cause. Different levels of vibration attenuation were accomplished at varying speeds in the x and z directions by placing DVA at different positions on the handlebars. Notably, the DVA showed a significant attenuation level between 59% and 68% in the biodynamic x-direction at speeds ranging from 30 to 50 km/h. This research provides valuable insights into the effectiveness of the DVA in reducing motorcycle handle vibration and highlights the significance of various design parameters for optimal vibration damping. The findings could improve ride comfort and reduce health risks associated with prolonged motorcycle use. Further development and optimization of DVA systems hold the potential for enhancing the overall riding experience and rider safety
