Abstract:
Objective To investigate the influences of mechanical crush induced by the sustained-Gxacceleration during arrested landing process on pilot's heart and lung in order to evaluate the risks of injury . Methods A high geometric accuracy ,rigidity-viscoelasticity finite element model of human heart ,lung and chest bones were built based on anatomical data and the material properties of different tissues obtained from published literature .The finite element dynamic explicit was conducted for analyzing the responses of the human heart and lung during typical arrested landing process . Results The simulation study demonstrates that -Gxwould generate impact stress on human heart and lungs and cause the relative displacement between heart ,lungs and chest bones .It presents the-Gxinduced mechanical crush influence on the aircraft carrier pilot during arrested landing .
