AI Technical Summary
The buffer springs of existing crash barriers deform greatly when subjected to external impacts, resulting in poor buffering performance. After prolonged use, their elasticity deteriorates, leading to poor buffering effect of the barriers.
The system employs a combination structure of protective netting and dampers. The protective netting is connected by a fixed frame, and the damper is connected between the two protective netting bodies to form a two-stage buffer, reducing rigid impact and absorbing energy through the damper.
It improves the guardrail's impact resistance, reduces damage to vehicles and people, and extends the guardrail's service life.
