Abstract

Subjective evaluation on whole-body vibration experienced in car was investigated. Vertical acceleration was measured at the seat floor as well as on the seat pan of a compact car when driving over two types of road surfaces. Apart from that, vibration transmissibility of 11 subjects participated in the study was also measured. The various body parts measured were right thigh, under the buttock, lumbar, upper back and head (in x-, y- and z-axes). The amplitudes measured from the seat floor were from 0.3 to 0.8 m/s2 BS6841 W d frequency weighted r.m.s. The frequency interval band-pass filtered was from 0.5 to 80Hz for the vibration measurement but only up to 40Hz for the transmissibility investigation. Relationship between the objective method and the subjective response were shown through Steven's Power Law exponent, β. From the analysis, it was found that β was around 1.2-1.3. Vibration transmissibility results show agreement with previous literatures where the primary resonances were between 4-9 Hz. It was also shown that there were only slight change with the different head and back condition except for x- and y-axes for head transmissibility. Although it was a field test, with a limited number of subject, inter-variability was shown to be having no significant difference (p=0.3 to p=0.9).
