“…In the next step, we will develop a neck protection system such as neck brace or inflatable restraint system using current model and cadaver tests. However, because the human model analysis is based on the multi-bodies theory, and there are some differences in biomechanical properties between Hybrid III and a living human being [6,7,14], the model needs to be perfected in flexibility and elasticity. Pain and Challis [8] developed a four-body segments wobbling mass model to simulate a drop landing considering the influence of the soft tissue motion on ground reaction forces, joint torques and joint reaction forces.…”

When a spacecraft lands on the earth by parachute, the crewmen will be subjected to a high-level landing impact which could cause their body injuries in case of emergency. The purpose of this investigation was to analyse the human neck injury risk under the high-level landing impact, and to provide useful information for the protection design of the human-seat system in the spacecraft. On the basis of impact test, a mechanical model of the human-seat system was developed, and the acceleration responses at the seat and cushion were simulated using the finite element method. After the model was calibrated and validated, the forces and moments in the human neck were calculated. The degree of the human neck injury can be judged according to the standard of the human neck injury index (N ij < 1). The results showed that when both horizontal and vertical dropping velocity reach 7.5 m/s, the compressive force and extension moment in the human neck were, respectively, 6.58 kN and 100 Nm; and the injury index of the human neck was 1.81 (more than the critical value 1). It is concluded that under the high-level landing impact, the first reason for cervical fracture is the compressive force, and the second is the extension moment. It is necessary to take measures to reduce them to levels less than tolerance limits.

In the development process of new solutions for rider protection, finite element (FE) simulations of motorcycle to car crashes represent a way to reduce costs and time. This paper focuses on the development and validation of an FE virtual environment for complete crash test scenarios and its use to evaluate the head and neck injuries. Models are validated through comparison of numerical and experimental data and, aiming at performing quantitative analyses, a new approach (named injury rating) for injury evaluation is proposed. The virtual environment is applied, as test case, to the simulation of eight crash scenarios selected from the ISO 13232 standard. The results are presented and discussed to demonstrate the potentialities of the approach in designing new rider protective devices.

Human has a strong spine which can generate dynamic and flexible motion. We focus on its mechanisms and implement them to a robot spine of a musculoskeletal humanoid through hardware design. First, this paper describes methods to develop the robot spine which has both strength and flexibility. We separated 3 vertebra groups from the spine like a human and applied some machining methods to each group. Second, we show a human-like muscle arrangement of the spine including planar muscles. The planar muscles have larger surface and power than linear muscles designed with conventional methods. Therefore, the spine can keep its posture even if it receives force by a dynamic arm motion. Finally, we show a variable stiffness system of the spine to resist an impact by which the spine structure and muscles damage. We tested the system in the situation of whiplash injury which often occur in rear-end collision in a vehicle body.
