Mechanical vibration and shock - Range of idealized values to characterize human biodynamic response under whole-body vibration (ISO 5982:2019, IDT)

Status: Valid

Scope
This document describes the range of idealized values of the apparent mass modulus and phase applicable to seated individuals with and without a back support subjected to x-, y- and z‑axis sinusoidal or broad-band random vibration and to standing individuals subjected to z‑axis sinusoidal or broad-band random vibration under specific experimental conditions. Additionally, this document describes the range of idealized values of seat-to-head transmissibility modulus and phase applicable to seated individuals without a back support subjected to z‑axis sinusoidal or broad-band random vibration. The ranges of idealized values defined in this document are considered to be valid for subjects on a rigid seat (or standing on a rigid platform for z-axis only), with feet supported and vibrated. The range of idealized seat-to-head transmissibility values is considered to be applicable also to the condition with the feet hanging freely. For seated individuals subjected to sinusoidal or broad-band random vibration, the apparent mass values are defined over the frequency range of 0,5 Hz to 10 Hz for the x‑axis and y‑axis, and over the frequency range of 0,5 Hz to 20 Hz for the z‑axis. The frequency and amplitude characteristics of the vibration fall within the range for which most vibration exposure is likely to predominate while driving vehicles such as agricultural tractors, earth-moving machinery and fork-lift trucks. Application to automobiles is not covered by this document in view of the lack of a meaningful database for conditions involving posture and vibration excitation levels most likely associated with car driving. The upper and lower values of modulus and phase defined at each frequency for each of the biodynamic response functions considered represent the range of most probable or idealized values. The middle values represent overall weighted means of the hum ...
