Road accidents cause considerable losses to road users and to society. The steady increase in the number of vehicles leads to increased traffic volume. Therefore, there is a real need to improve passenger safety by developing passive safety systems. This article presents the results of experimental tests of structures absorbing kinetic energy, which could be used in the front section of a vehicle in order to reduce the consequences of passenger car head-on collisions. A number of crash tests of selected structures were conducted under various load conditions. An analysis was carried out of parameters enabling the authors to assess the level of energy absorption by the absorbers made, and compare these to absorbers available on the market. The tests carried out made it possible to determine energy absorption capability of the crash boxes prepared and to identify a structure exhibiting the most advantageous properties from the point of view of its prospective use. Of all of the absorbers analysed, in the context of energy absorption, it was the absorber made of glass-fibre-reinforced polyphenylene sulphide that produced the most advantageous results. Nonetheless, favourable results were obtained for all of the structures tested.
道路交通事故给道路使用者和社会造成了巨大损失。车辆数量的稳步增长导致交通流量增加。因此，通过开发被动安全系统来提高乘客安全性确实很有必要。本文介绍了动能吸收结构的实验测试结果，这些结构可用于车辆前部，以减少乘用车正面碰撞的后果。在各种负载条件下对选定结构进行了多次碰撞测试。对一些参数进行了分析，使作者能够评估所制造的吸收器的能量吸收水平，并将其与市场上现有的吸收器进行比较。所进行的测试能够确定所制备的碰撞盒的能量吸收能力，并从其预期用途的角度识别出具有最有利特性的结构。在所有分析的吸收器中，从能量吸收的角度来看，由玻璃纤维增强聚苯硫醚制成的吸收器产生了最有利的结果。尽管如此，所有测试结构都获得了良好的结果。
