It is calculated as a cumulative sum of the weighted acceleration at the fourth power. The fourth power is used to give more weight to the transient event of the signal over the periodic event. Therefore, this indicator must be used to assess the effect of shock on human health and comfort. The VDV is calculated for each channel and expressed in m/s^(1.75).<br> | ||
