摘要：
To explore the effect of helmet on neck injury of pilots in-flight, numerical simulations were carried out on four different helmets during sharp turn and stable hover condition based on the established head-neck multi-body dynamic model. Combining the muscle force, intervertebral force and moment, and the neck injury index Nij, the neck injury of pilots was evaluated and predicted. The results show that the dynamic responses of the model are in agreement with the experimental results, with fair bio-fidelity. In the same flight condition, the wearing of helmet B shifts the center of head forward and increases the muscle force of the trapezius accordingly. For the same cervical segment, the axial compression force for helmet B and the extension moment for helmet C is maximum respectively. The value of Nij for all simulated conditions is less than 0. 5, which conforms to the safety requirements in aviation. The mass of helmet B and helmet C are close, while the mass center of helmet B is forward compared to helmet C, which indicates the anteroposterior position of helmet has an important effect on neck injury. This study provides insights for the optimization of pilot’s helmet and its effect on pilot’s neck injury. © 2022 Beijing University of Aeronautics and Astronautics (BUAA). All rights reserved.
