项目摘要

The problem of human falls, particularly among the elderly, is one that can result in serious injuries, such as a soft tissue injury or a bone fracture, or even result in death depending on the severity of the accident.The purpose of this study's goal was to find out the factors that may have a significant impact on the severity of fall injury as a result of a fall, and how these factors may influence the severity of the fall injury. In an investigation that we conducted, we investigated soft tissue stiffness that may play a significant role in determining the extent of injury sustained during a fall or any collision such as machine-human impact during a fall or collision for a variety of impact velocities during a fall or collision.It is highly likely that the upper arm will be damaged during a lateral fall or a second impact during a forward fall. Soft tissue stiffness in the upper arm was measured using a pendulum during a subject-based experiment. Soft tissue deformation and impacts can be measured using force sensors and ultrasonic technology.As a result of this study, we were able to demonstrate that different impact velocities result in different changes in the stiffness behavior of nonlinear soft tissues. In addition, we used a variety of indentation impactors to obtain the behavior of the stiffness of soft tissues during the impact of the impactor.

福尔斯是一个严重的摔伤问题，尤其是在老年人中，可能会导致严重的损伤，如软组织损伤或骨折，甚至导致死亡，这取决于事故的严重程度。本研究的目的是找出可能对摔伤严重程度产生重大影响的因素，以及这些因素如何影响坠落伤害的严重程度。在我们进行的一项调查中，我们研究了软组织硬度，它可能在确定跌倒或任何碰撞（如跌倒或碰撞期间的机器-人碰撞）期间持续损伤的程度方面发挥重要作用，在跌倒或碰撞期间的各种冲击速度下，上臂很可能在侧向跌倒或向前跌倒期间的第二次冲击中受损。在基于受试者的实验期间，使用摆锤测量上臂中的软组织刚度。软组织的变形和冲击可以使用力传感器和超声波技术来测量。作为这项研究的结果，我们能够证明，不同的冲击速度会导致非线性软组织的刚度行为发生不同的变化。此外，我们使用了各种压痕冲击器，以获得在冲击器的冲击软组织的刚度的行为。
