Summary:

In India, small car segment is having maximum sale, whichincludes cars like Maruti 800, SUZUKI Swift, Maruti Alto, TataIndica, et cetera Driver seat is one of the main aspects to beconsidered while defining comfort in a moving vehicle. The currentanalysis concentrates on driver seat because driver comfort is ofmain concern since it is the most occupied seat in any vehicle andthe occupancy is for longer duration. In addition to sitting, thedriver's job is to manipulate different controls andconcentrate parallely on many aspects. The research work aims atstudying the vertical vibrations transferred to the human body viaseat.The work is an attempt towards studying dynamic characteristicsof driver seat for comfort through objective evaluation. Forobjective evaluation, two tests were conducted; Seat EffectiveAmplitude Transmissibility (SEAT) test and Ride Comfort Index testunder two different conditions, id est, car level and seat leveltesting on Car "A" and Car "B." Both tests werecarried out under controlled conditions.Car level test was carried out on 4-Poster simulator, which cansimulate exact road conditions in vertical direction whereas seatlevel testing is done on electro-dynamic shaker, which simulatessinusoidal signals. Results of experimentations, i.e.,accelerations at seat base and seat mount were compared withreference standard ISO 2631-1(1997) which indicated average RootMean Square (RMS) of Car "A" and Car "B" is0.007 and 0.008 Km/s₂ respectively. Hence according to ISO2631-1(1997), both cars fall into "fairly uncomfortablezone". SEAT Test revealed transmissibility in two differentpositions (front most and rearmost position). In front mostposition, transmissibility is 65.66% and 204% for Car "B"and Car "A" respectively, whereas transmissibility is63.56% and 145% for Car "B" and Car "A" inrearmost position of seat
