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 human data and define the target values for general
applications. Such applications can involve the development of mechanical analogues for laboratory seat
testing, or of functions to correct for the human interface when representing the body as a rigid mass,
or the development of analytical human body models to be used for whole-body vibration exposure
estimations or for seat and cushion design optimization.
