摘要
泡沫橡胶具备的缓冲、减震等阻尼性能在道路安全防护领域有着广泛的应用前景,而其在路用荷载作用下体现的动态力学响应是较为关键的问题。通过对泡沫橡胶材料进行动态周期性压缩试验,得到孔隙结构和应变率水平2个因素对路用阻尼性能的影响,论证了阻尼吸能效率与应变率水平及材料类型具有相关性。
With buffering and damping property foam rubber has a broad application prospect in the field of road safety protection,and the key problem is the dynamic response of foam rubber under dynamic loading.Through the environmental sensitivity test and dynamic periodic compression test of the foam rubber material,it is concluded that foam rubber has environment durability and energy dissipation property which related to strain rate and material category.
