A novel method of Improving Ride Comfort of Two Wheeler by Optimization of Seat Parameters. 2019-28-0013

Two-wheeler plays a significant role in personal transportation in India. People prefer two-wheelers, which has better fuel economy, comfort, and performance. It is vital to enhance comfort, as the seat is in direct contact with the user. Better user comfort improves the vehicle feel and behavior. Dynamic comfort analysis is necessary to understand and improve the vibration characteristics of the human-seat system. The vibration characteristics under analysis are Natural frequency, Maximum transmissibility, Attenuation frequency, and Transmissibility at 6 Hz. A test set-up was developed to collect data samples with different seat characteristics. The data collected from the seat are IFD, Hysteresis, Air-Permeability, Resilience, Thickness, and Mass. The relation between the seat parameters and vibration characteristic is established by statistically analyzing the data. Best seat was identified by ranking vibrational characteristics. Correlation analysis determines the best seat by subjective rating of the sample and seat vibration ranking. Keywords: Transmissibility, two-wheeler seat, Polyurethane foam, Comfort and fatigue, correlations, ride comfort, Vibration Isolation,Optimization.
