The biodynamic responses of seated occupants exposed to whole‐body vibration have been mostly investigated in terms of apparent mass characteristics, which show negligible contributions due to exposure level. Considering that the severity of vibration exposure is related to the level and duration of exposure, the apparent mass responses cannot be used for assessment of the associated risks. Alternatively, the absorbed power characteristics of the seated vibration exposed occupants show strong dependence on the level of exposure. The measured data, expressed in terms of the vertical absorbed power, are analyzed to study the effects of sitting posture on the biodynamic response under whole‐body vertical vibration.

Abstract. In the paper there is presented a case study of a cabinet barrier for a car parking. The materials used for manufacture are changed with polymeric composites. A design is proposed for the cabinet and a manufacturing technology is considered. The composite material is designed, realized and tested with tensile test ant three bending test and the results are presented.

The paper presents some aspects about the dynamic response of the human body subjected to the vertical vibration in the travel inside the auto vehicle. There is a model presented in the specialized literature. This is transformed for the given study because was necessary to realize the vertical vibration along the human body. There are two different studies: using a linear lumped parameter systems seat ‐ human body model; using a nonlinear lumped parameter systems seat‐human body model. (© 2006 WILEY‐VCH Verlag GmbH & Co.

In a seated posture into an autovehicle, humans are most sensitive to whole‐body vibrations under low‐frequency excitation. This research is focused only on the effect of the backrest angle on the biodynamic response functions. In this paper there are present the results of investigations for 10 participants, whose mean body mass was 61.4 kg. For the biodynamic responses of a seated human body subjected to vertical vibrations, three automotive postures was study: without backrest support, with backrest inclined 7° and respectively 15°, by measurement of transmitted vibration in two different situations: with belt and respectively without this. Knowledge of human responses to vibration provides information about the position of backrest support to mitigate vibration transmitted through the body ensuring the health, comfort and performance.
