摘要
以ANSYS Workbench为仿真计算平台,通过非线性显示动力学,探讨护栏板变形量、护栏能量吸收能力以及质量块加速度曲线;对带加强筋的自升高式护栏防阻块和传统六棱柱形防阻块进行碰撞分析对比,探究2种防阻块高度提升量和能量吸收能力情况,并进行参数优化设计。分析结果表明:该护栏吸收碰撞能量能力强,抵抗变形能力优越;带加强筋的自升高式护栏防阻块性能优于传统防阻块,可为护栏的工程应用提供有益参考。
The deformation, energy absorption ability of guardrail and mass acceleration curve were explored by means of non-linear explicit dynamics in the simulation platform of ANSYS Workbench. Comparison on the impact of stiffened height-adaptive obstruction block and the traditional hexagonal prism-shaped obstruction block was conducted in order to study their lift height and energy absorption capability, and parameters were optimized. The results show that the guardrail is superior in impact energy absorption and distortion resistance; stiffened height- adaptive obstruction block beats the traditional obstruction block in performance.
