摘要
洞悉我国冷藏车后下防护装置的发展,比较冷藏车传统和现阶段的后下防护装置研究状况。分别阐述了传统和现阶段的几种典型的后下防护装置,并对其性能进行分析。对比两阶段的后下防护装置,发现新型的后下防护装置在高速被动防撞时具有多级吸能、可翻转等优点,具有良好的避免钻撞、吸能防护作用。新型的后下防护装置配套防碰撞预警系统可以实现主动防撞和被动防撞相结合,但由于其造价高推广价值不大,故仍需要进一步改进。
Giving insight into the development in rear under-run protective device of refrigerator car,comparing the traditional and current research on rear under-run protective device of refrigerator car,this paper expounds several typical rear under-run protective device between the traditional and present stage,and analyzes their performances respectively.Compared to two stages＇ rear under-run protective device,when the truck was in passive anti-collision at a high speed,the new types of rear under-run protective device have the advantages of multistage energy absorption,reversible and so on.When the new type of rear under-run protective device was supported by collision warning system,the combination of active anti-collision and passive anti-collision came true,but due to its high cost it＇ s promotion is of little value,it still needs to be improved further.
