汽车与缆索护栏碰撞是一个极为复杂的力学过程,影响其动力反应的因素很多。碰撞后的护栏系统如横梁、立柱、地基的变形情况以及碰撞车辆的变形、运动轨迹、倾覆等情况也极为复杂,而且有很大的随机性。根据缆索护栏的受力特点,对碰撞过程进行适当的假设,建立车辆与缆索护栏碰撞的简化计算模型,可为高速公路护栏的设计、施工提供借鉴。
Car and cable barrier collision is a very complex mechanical process, the impact of the dynamic response of many factors. After the collision of guardrail systems such as beams, columns, the deformation of the ground and the collision vehicle deformation, trajectory, overturning and so on are also extremely complex, but also a great randomness. According to the characteristics of the cable guardrail, the appropriate assumptions of the collision process are established, and a simplified calculation model of the collision between the vehicle and the cable guardrail is established, which can provide reference for the design and construction of the highway guardrail.
