Abstract Understanding the impact severity of unmanned aircraft system (UAS) collisions with the human body remains a challenge and is essential to the development of safe UAS operations. Complementary to performing experiments of UAS collisions with a crash dummy, a computational impact model is needed in order to capture the large variety of UAS types and impact scenarios. This article presents the development of a multibody system (MBS) model of a collision of one specific UAS type with the human body as well with a crash dummy. This specific UAS type has been chosen because data from experimental drop tests on a crash dummy is available. This allows the validation of the MBS model of UAS impacting a crash dummy versus experimental data. The validation shows that the MBS model closely matches experimental UAS drop tests on a crash dummy. Subsequently, the validated UAS MBS model is applied to predict human body injury using a biomechanical human body model. Head and neck injury from the frontal, side and rear impact on the human head are predicted at various elevation angles and impact velocities. The results show that neck injury is not a concern for this specific UAS type, but a serious head injury is probable.

无人机系统与人头碰撞的多体系统建模

摘要 了解无人驾驶飞机系统 (UAS) 与人体碰撞的严重程度仍然是一项挑战，并且对于 UAS 安全操作的发展至关重要。作为对 UAS 与碰撞假人进行碰撞实验的补充，需要一个计算影响模型来捕捉各种 UAS 类型和影响场景。本文介绍了一种特定 UAS 类型与人体以及碰撞假人碰撞的多体系统 (MBS) 模型的开发。之所以选择这种特定的 UAS 类型，是因为可以获得碰撞假人的实验跌落测试数据。这允许验证 UAS 影响碰撞假人与实验数据的 MBS 模型。验证表明，MBS 模型与碰撞假人上的实验性 UAS 跌落测试非常匹配。随后，经过验证的 UAS MBS 模型用于使用生物力学人体模型预测人体损伤。在不同的仰角和撞击速度下，预测从正面、侧面和背面撞击人体头部造成的头部和颈部损伤。结果表明，颈部受伤不是这种特定 UAS 类型的问题，但很可能是严重的头部受伤。
