半刚性护栏

重型车辆与半刚性护栏碰撞的有限元分析

Finite Element Analysis of Impact between Heavy Vehicle and Semi-rigid Guardrail

其后详细介绍了高度自适应半刚性护栏的设计思想，包括设计初衷，结构形式，工作原理等。

Then the design idea about semi-rigid guardrail with an adaptive height is introduced in detail , including design original intention , structure form and design principle .

进一步使用有限元软件ANSYS及LS-DYNA对汽车-柔性护栏碰撞系统进行数值模拟，通过改变护栏结构参数改进半刚性护栏设计。

Ultimately determined by numerical simulation as the research method , using the finite element software ANSYS and LS-DYNA on car crash system for a flexible barrier to simulate the structural parameters improved by changing the barrier guardrail design .

半刚性护栏系统模型冲击实验研究

Impact Experiment of Semirigid Guardrail System Model

通过该实验系统开展了半刚性护栏系统的冲击实验研究，得到护栏系统的各部件在冲击条件下的变形特点。

The dynamic behaviors of the guardrail system under impact were fundamentally acquired and the features of the deformations of each component of the guardrail system were described .

鉴于现有的半刚性护栏结构在碰撞过程中高度迅速降低，这对于重心较高车辆极易造成侧翻事故。

Because of the height of existing guardrail declining rapidly during the collision , rollover accident is prone to happen for vehicles with a very high center of gravity .

本文从大系统观点出发，运用系统工程思想，提出将汽车-半刚性护撞护栏碰撞系统作为一个完整耦合的大系统，来研究半刚性护栏防撞新机理。

From the view point of large system and by applying the system engineering theory the collision protection system of semi_rigid fences for autos is looked as a complete and coupled macro_system so as to study the adequate mechanism of collision protection for semi_rigid fences .
