the passive safety of aircraft passengers is such an important aspect in the design of aircraft structures as strength and fatigue concerns. The development of methods and devices to prevent passenger injuries is the subject of continuous efforts. The mission is to minimize stresses and accelerations on passengers during a crash. Over the years, studies on crash phenomena have been focused on experimental tests, using full-scale structures and Anthropomorphic Test Devices (ATDs) to assess the consequences of impact phenomena on the human body. However, due to the high costs of experimental campaigns and the difficulty of controlling all relevant parameters, the need of efficient numerical models capable of validating experimental data has increased. This is specifically relevant for tests on ATDs.

关于使用混合减震器来提高坠机事件中商用飞机乘客的安全


飞机乘客的被动安全与强度和疲劳问题一样，是飞机结构设计中的一个重要方面。开发防止乘客受伤的方法和设备是我们不断努力的主题。任务是最大限度地减少碰撞过程中乘客的压力和加速度。多年来，对碰撞现象的研究一直集中在实验测试上，使用全尺寸结构和拟人化测试设备（ATD）来评估碰撞现象对人体的后果。然而，由于实验活动成本高昂且控制所有相关参数的难度，对能够验证实验数据的高效数值模型的需求不断增加。这与 ATD 测试特别相关。
