摘　　要：文中利用落锤仪对波纹夹层吸能结构进行横向低速冲击试验,基于试验结果讨论了冲击速度、填充情况等参数对波纹夹层结构冲击响应的影响。结果表明:波纹夹层吸能结构内部填充泡沫能显著减少结构变形,改变结构失效模式,在增大撞击力的同时,也会增加撞击持续时间,显著提高了结构的吸能性能.The transverse low-speed impact test of corrugated sandwich energy-absorbing structure was carried out by using drop hammer instrument.Based on the test results,the influence of impact speed,filling condition and other parameters on the impact response of corrugated sandwich structure was discussed,which provided experimental data reference for the application of corrugated sandwich energy-absorbing structure in bridge anti-collision facilities.The test results show that filling foam in the corrugated sandwich energy-absorbing structure can significantly reduce the structural deformation and change the structural failure mode.Meanwhile,the impact force will increase and the impact duration will also increase,which significantly improves the energy absorption performance of the structure.
