对人尸体下颌骨颏部进行撞击实验，用以探讨不同撞击参数与影响损伤严重程度的撞击力大小之间的相互关系，以期为致伤机理和医学防护提供理论依据。实验描述了下颌骨在撞击作用下的动态响应规律，表明颏部所承受的撞击力大小与时间成半个正弦波函数关系。颏部在撞击载荷作用下所承受的作用力大小与撞击速度、撞击质量、撞击方向以及撞击砣材料有关，可为医学防护提供依据。 The impact experiment on the mandible chin of human corpse was conducted to explore the relationship between different impact parameters and the impact force impacting on the severity of injury so as to provide a theoretical basis for the injury mechanism and medical protection. The experiment describes the dynamic response of the mandible under impact, indicating that the impact force on the chin is a half sine wave function with time. The force exerted by the chin on the impact load is related to the impact velocity, the impact mass, the direction of the impact and the material of the impact 砣, which may provide the basis for medical protection.
