Vibration reduction of human body biodynamic response in sitting posture under vibration environment by seat backrest support

Vibration reduction of human body biodynamic response in sitting posture under vibration environment by seat backrest support

Four-degree-of-freedom (4-DOF) human–chair coupling models are constructed to characterize the different contact modes between the head, chest back, waist back and backrest. The seat-to-head transfer ratio (STHT) is used as an evaluation metric for vibration reduction effectiveness. The simulated vi...

Zusammenfassung:Four-degree-of-freedom (4-DOF) human–chair coupling models are constructed to characterize the different contact modes between the head, chest back, waist back and backrest. The seat-to-head transfer ratio (STHT) is used as an evaluation metric for vibration reduction effectiveness. The simulated vibration reduction ratio of the model is close to the experimental results, which proves the validity of the model. The peak STHT is obviously reduced (P
