The influences of trunk horizontal vibration to the head-neck complex

摘要

The head-neck complex (HNC) is modeled and identified when the trunk of seated human body is exposed to the horizontal (fore-and-aft) vibration. According to the results of the frequency response function of the system, a double-inverted pendulum is considered as a model for the HNC. The frequency domain identification method is used to identify the HNC. The viscoelastic parameters of the neck are also obtained. Good agreement is obtained between the experimental data and simulation.
