Lightweight design and post-impact attitude stability of extra-high grade guardrail based on 700L high-strength steel
To address the issues of excessive self-weight and insufficient post-impact attitude stability inherent in traditional HA-level (extra-high grade) beam-post guardrails due to oversized cross-sections, this paper proposes a lightweight design method utilizing 700L high-strength alloy steel. Through topology optimization...
