摘要

本文的目的是介绍一系列动态测试,用于测试PROBAR系统的防护和安全屏障,该系统由STRIX Chomutov公司根据PAS 68:2013标准开发。测试的目的是评估障碍物如何抵抗冲击,以及它是否能吸收施加在它身上的能量。在两种类型的冲击配置下,对该装置的机械性能进行了验证。重点放在障碍物和车辆在碰撞期间以及碰撞后短时间间隔内的行为上。在评估冲击试验的标准方面,可以说试验2超出了理论头部撞击速度(THIV)标准20 km h - 1,而试验1没有超过极限值。然而,其他标准(ASI, PHD, HIC, 3ms)的所有值都在规定的范围内,并且安全屏障符合允许认证的要求标准。

Dynamic tests of the protective and security barrier system probar
The purpose of this paper is to present a series of dynamic tests for testing the protective and security barrier of the PROBAR system, developed by STRIX Chomutov, a.s., according to the PAS 68:2013 standard. The goal of the tests was to assess how the obstacle resist impacts and whether it can absorb the energy exerted on it. Verification of the mechanical properties of the device was performed in two types of impact configurations. Emphasis was placed on the behaviour of both the obstacle and the vehicle during the impact and in the short time interval after the collision. In terms of criteria for evaluating the impact tests, it can be stated that Test 2 exceeded the Theoretical Head Impact Velocity (THIV) criterion by 20 km h−1, while Test 1 did not exceed the limit value. However, all values for other criteria (ASI, PHD, HIC, 3ms) were within the specified limits, and the safety barrier met the required criteria which allows to be certificated.
