Abstract:
Objective To compare the differences of neck injury risks for different mummies during arrested landing on naval vessels. Methods Based on the established dynamic model of dummy-belt-seat systems and mechanical model of head-neck, with the acceleration curve at seat base during typical arrested landing reported in the literature as the input, numerical simulation was conducted to test the validity of the model, and the axial force, shear force， bending moment of typical joints in dummy neck during arrested landing were obtained. Results The injury index Nkm of 95 percentile dummy was higher than that of 5 percentile dummy. The injury index Nij of the dummy’s upper and lower cervical spine was smaller than 0.2, meanwhile the Nkm was around 0.65. Conclusions During arrested landing, human neck was much easier to get hurt due to the shear force. The research findings can provide data support for evaluating neck injury risks of pilots with different sizes during typical arrested landing process.
