The Used of Pedal-Pad Effective Amplitude Transmissibility Value to Predict Size of Comfortable Pedal-Pads

Vibration transmissibility from a car body to pedal-pad could result to drivers discomfort and fatigue, which may lead to health problems. Vibration transmissibility occurs when the vehicle engine is turned on and vibration is transmitted from the car body to pedal-pad in this research Pedal-pad effective Amplitude Transmissibility (PEAT) value was used to predict suitable size of the pedal-pad that could provide comfortable operation of the pedal. In this study, the variables are the three different sizes of pedal-pads and data was recorded while the car was moving on the road at constant speed with three different sizes of pedal-pads. The data was measured in root mean square (r.m.s) unit, of the frequency weighted acceleration (m/s2) for every minute. The finding of the study shows that percentage PEATr.m.s of the three different sizes of pedal-pad is greater than 100%. It shows that vibrations to pedal-pads are greater than vibration from the car body consequentially it means that the foot on the pedal is exposed to higher vibration transmissibility than the foot on the floor.
