The present study proposes a 15-degrees of freedom multibody model of semi-supine humans to estimate the injury risk to a space capsule occupant during landing. The model consists of five body segments representing head-neck, thorax-arms, abdomen, thigh-pelvis, and leg. The semi-supine human model is calibrated using transmissibility responses of each body segment obtained from parallel vibration testing on the human subjects. The occupants' dynamic response to impact acceleration incurred during landing is simulated through the developed model. The model estimated the highest acceleration at the thorax and head, respectively, in the chest and spine directions. The impact acceleration of 20g is observed to violate the low injury risk criterion at the seat angle of 30°. The proposed human body model can be employed to design and test the effectiveness of attenuation and restraint systems of a space capsule.
