Wave-shaped guardrail plate and wave-shaped guardrail
The invention discloses a wave-shaped guardrail plate and a wave-shaped guardrail, and belongs to the technical field of road guardrail plates. The wave-shaped guardrail plate comprises more than two wave crest parts and wave trough parts connected with the adjacent wave crest parts; the top section of the crest part is a straight line, and the length of the straight line is smaller than the distance between two arc-shaped end points of the crest part. Compared with a traditional wave-shaped guardrail plate, the wave-shaped guardrail plate has the advantages that the inertia moment of the wave-shaped guardrail plate is increased by more than 18% by optimizing the linear design of the top section of the wave crest part of the wave-shaped guardrail plate, and the optimized wave-shaped guardrail plate effectively reduces the deformation of a guardrail in collision, improves the energy absorption performance and reduces the acceleration of the mass center of a vehicle; the risk that the out-of-control vehicle runs out of the road is reduced to a certain extent, and the safety of vehicle passengers can be more effectively protected.
本发明公开了一种波形护拦板及波形护栏，属于公路护拦板技术领域。所述波形护拦板，包括两个以上波峰部及相邻波峰部连接的波谷部；所述波峰部的顶部截面为直线，直线的长度小于波峰部弧形两端点的距离。相比与传统波形护拦板，本发明通过优化波形护拦板波峰部顶部截面的线形设计，使波形护拦板的惯性矩提高18％以上，优化后的波形护拦板有效地减少了碰撞中护栏的变形量，提高能量吸收性能和降低车辆质心加速度，在一定程度上降低失控车辆驶出路外的风险，能够更有效地保护车辆乘员的安全。
