摘要

锥形泡沫填充结构结合了泡沫填充结构与锥形结构的优势，具有优异的吸能性和抵抗失稳变形的能力。研究了具有不同横截面的泡沫填充多边形单锥管（FSPTTs）与泡沫填充多边形双锥管（FBPTTs）在四种冲击角度下的耐撞性。采用多准则评估方法(COPRAS)对不同横截面的泡沫填充单锥管与泡沫填充双锥管的综合耐撞性进行了评估。评估表明：综合考虑多种冲击角度时，圆形截面泡沫填充单锥管较其他截面泡沫填充单锥管具有更好的耐撞性；圆形截面泡沫填充双锥管较其他截面泡沫填充双锥管具有更好的耐撞性。最后，针对圆形截面泡沫填充单锥管与圆形截面泡沫填充双锥管，以最大比吸能和最小峰值力为目标，采用非支配遗传算法对这两种结构在四种冲击角度下进行了多目标优化。结果表明：当冲击角度从0°变化到10°时，两种结构的pareto曲线变化不大，而当冲击角度从10°变化到30°时，冲击角度对pareto曲线形状和位置有显著影响；在冲击角度为0°和10°时，圆形截面泡沫填充双锥管的耐撞性优于圆形截面泡沫填充单锥管，而在冲击角度为20°和30°时，圆形截面泡沫填充单锥管的耐撞性优于圆形截面泡沫填充双锥管。实际应用中，可以根据工程需要选择合适的结构。

Abstract

The foam-filled taper tube,which combines the advantages of foam-filled structures and taper structures,has excellent abilities of energy absorption and buckling deformation resisting.The crashworthiness of foam-filled single polygonal tapered tubes(FSPTTs) and foam-filled bitubal polygonal tapered tubes(FBPTTs) under oblique impact loading was studied.A complex proportional assessment and evaluation method(COPRAS) was adopted to evaluate the comprehensive crashworthiness of FSPTTs and FBPTTs.It is found that the foam-filled single circular (FSC) tube and foam-filled bitubal circular (FBC) tube respectively perform better than FSPTTs and FBPTTs with other cross sectional configurations.The multiobjective optimization was conducted on the FSC and FBC tubes under four different impact angles to maximize the specific energy absorption and peak force.The results show that the Pareto curves of both FSC and FBC tubes have only little change when the impact angle changes from 0° to 10°，while the impact angle has significant effect on the Pareto curves when the impact angle changes from 10° to 30° .The FBC tube performs better when the impact angle is 0° or 10°，while the FSC tube performs better when the impact angle is 10° or 20° .Appropriate structures can be chosen to meet practical application requirements.
