Vehicle refinement should include a consideration of the discomfort likely to be caused by
vibration. This paper reviews the measurement, the evaluation, and the assessment of …

Through continued collaboration and the sharing of ideas, data, and results, the
international community of researchers and practitioners has developed an understanding …

Since vehicle ride comfort represents an important criterion for the customer and the vehicle
development process consumes a great deal of time and cost, increased efficiency and …

The evolution of indices of fatigue, discomfort, and performance of subjects seated for long
duration (150min) in car seats were studied (n= 11). Four experimental configurations were …

Vibration in the three translational (fore-and-aft, lateral and vertical) and the three rotational
(roll, pitch and yaw) axes of the head has been measured during exposure to whole-body …

This paper presents an optimization of a four-degrees-of-freedom quarter car seat and
suspension system using genetic algorithms to determine a set of parameters to achieve the …

It is currently assumed that the same frequency weightings, derived from studies of vibration
discomfort, can be used to evaluate the severity of vibration at all vibration magnitudes from …

The biodynamic response characteristics of 13 male and 14 female seated subjects,
exposed to vertical vibration, are characterized under different postural conditions. The …

Current methods for evaluating seat vibration to predict vibration discomfort assume the
same frequency weightings and axis multiplying factors can be used at the seat surface and …

This study revealed the mechanism of long-term passenger vibration discomfort in high-
speed trains and proposed a novel evaluation model to assess it, while the most popular …
