| Abstract: | Vibration tests were conducted on 28 volunteers by means of white noise excitation with a wide frequency range and various levels to more accurately understand the vertical vibration characteristics of seated Chinese human bodies.Apparent mass was obtained for each volunteer.The model with 3 degrees of freedom suggested by ISO 5982-2001 was employed to describe the vibration characteristics.An error function defined in terms of both amplitude and phase information of apparent mass was used to identify all m... |
