Experimental and finite element analysis of a two wheeler handlebar subjected to semi active constrained layer damping treatment

The study investigates the transient vibration analysis of two-wheeler handlebar and the optimization of vibration damping using constrained layer Magnetorheological Elastomers (MRE). The research explores how varying magnetic field strengths affect the damping properties of MRE, which is strategically implemented in the handlebar of a two-wheeler with a view to reducing vibrations and improving rider comfort. This study is a combination of numerical simulation and experimental data to highlight the effectiveness of semi-active damping systems under different magnetic fields. A sandwich beam was prepared at the laboratory for the damping material, and it was tested for the variation in damping ratio when the magnetic field was varied. The results demonstrate significant improvements in vibration attenuation when MRE damping ratios are optimized by varying the magnetic field, resulting in enhanced structural integrity and rider comfort.
