Research on vertical vibration characteristics of human body under standard sitting posture

Abstract

At present, the design of the vehicle guided by the vertical vibration characteristics of the human body is mainly based on the ISO5982-2001 standard, but the standard is mainly based on the body structure characteristics of Europeans and Americans, and is not necessarily suitable for the physique of Chinese. In order to better guide the design of Chinese vehicles, this paper built a test bench for the study of vertical vibration characteristics of the human body and conducted relevant experiments on 20 volunteers. The relevant data of 20 volunteers such as apparent mass, drive point mechanical impedance and seat-head transfer function were obtained through the experiment, and compared with the international standard ISO5982-2001. It is found that the vertical vibration characteristics of the human body under the standard sitting conditions of the Chinese are quite different from the ISO5982-2001 standard, so the relevant indicators of the ISO5982-2001 standard on the vertical vibration characteristics of the human body under the standard sitting conditions are not applicable to the design of guiding Chinese vehicles.Keywords-vertical vibration characteristics of human body, apparent mass, driving point mechanical impedance, seat to head transfer function
