Recurrent impact protection devices usually need to dissipate large amounts of energy to prevent damage to the infrastructure they protect and to make efficient use of them. This requires that protection devices consider some type of damping and have some mechanism to recover their original form. In this study a novel device is proposed, capable of absorbing a large part of the energy imposed by impact loads and recovering its original form autonomously. The device proposed in this article is composed of rigid parts with articulated joints, an elastic element that allows the recovery of its shape and an element that dissipates energy by friction. The necessary equations were developed to describe the non-linear behavior of the device and parametric simulations of the proposed model were performed to describe the dynamic interaction between the device and a mass that impacts. Additionally, a scale model of the device was constructed to be experimentally tested, which allowed to verify the effectiveness in the dissipation of energy, the reduction in the force transmitted to the support structures and the decrease in the rebound speed of the impacting mass. An error parameter was defined for a load-unload cycle between experimental results and analytical calculations. The error considers both the impact force and the dissipated energy, obtaining values of up to 6%. The energy absorption capacity of the device –between 83% and 93% of the impact energy– was verified experimentally, as well as the reduction of the impact speed –between 91% and 96%–.

循环冲击保护装置通常需要耗散大量能量，以防止损坏其保护的基础设施并有效利用它们。这就要求保护装置考虑某种类型的阻尼并具有某种机制来恢复其原始形状。在这项研究中，提出了一种新颖的设备，该设备能够吸收冲击载荷施加的大部分能量，并自动恢复其原始形式。本文提出的装置由具有关节接头的刚性部件，允许其形状恢复的弹性元件和通过摩擦耗散能量的元件组成。开发了必要的方程式来描述设备的非线性行为，并对提出的模型进行了参数模拟，以描述设备与撞击质量之间的动态相互作用。另外，该装置的比例模型被构造为要进行实验测试，从而可以验证能量耗散，传递到支撑结构的力的减小以及冲击质量的回弹速度的减小的有效性。在实验结果和分析计算之间的装卸循环中定义了一个误差参数。该误差同时考虑了冲击力和耗散的能量，得出的值高达6％。该装置的能量吸收能力（介于冲击能量的83％至93％之间）已通过实验验证，
