Effect of Different Seat Pan Angles and Feet-Floor Interactions on Human Body Response Using a Biodynamic Model 2019-01-0169
abstract：In recent years, study on the ride comfort of vehicles has attracted wide attention. The vibration caused by the road is transmitted to the human body through the tire, suspension, vehicle body, and the seat. Since the human body is in contact with the seat and the vibration is transmitted directly to the human body through the seat, the seat pan angle plays an important role on the vibration response of the human body. Previous studies have explored the effects of different backrest designs on human vibration response, but ignored the effects of different seat pan angles on human vibration response. Therefore, this paper will use a 14-DOF human biodynamic model combined with a 6-DOF seat model to study the effects of seat pan angles on human vibration response. Three models are proposed: the first model has a seat pan angle 13°, the second model has a seat pan angle 15°, and the third model has a seat pan angle 17°. In addition, the interface between the biodynamic model and vehicle floor has two ways: rigid connection and soft connection.
