Abstract

This research proposes a technique to reduce vibration transmission in vehicle seats by employing Silicon rubber and Neoprene rubber sheets of varying thicknesses between the seat base and seat mount. The aim is to optimize the acceptable vibration level and enhance vibration isolation. The study incorporates the latest advancements in the field of vibration transmission and the vibration properties of car seats. Various rubber sheets, including 3 mm and 4 mm of neoprene rubber, as well as 3 mm and 4 mm of silicone rubber, are mounted between the seat mount and seat base to act as a vibrating table. The research also examines current sensor technologies used to measure the transmission of vibrations from the car's base to the seat. Experimental investigations reveal that using a 4 mm Neoprene rubber sheet on the seat base minimizes transmissibility, resulting in an identified RMS Acceleration of 0.014889 km/s2, RMS Velocity of 6.62675 cm/s, and Displacement of 1.0625 mm. By considering the progress in new findings and the introduction of novel technologies, this research explores the future research directions in this field
