| 摘 要： | 对泡沫铝合金部分填充方形铝管三点弯曲性能进行研究。研究发现:泡沫铝部分填充管承受的弯曲载荷和吸收的能量与空铝管相比有显著的提高,变形模式从单褶皱模式变为多褶皱模式;泡沫铝部分填充管承载能力和能量吸收能力随着泡沫铝孔隙率的减少而提高,但是达到极限载荷的位移变短;与全填充管相比,泡沫铝部分填充管仍然可以承受较高的载荷,同时有效降低结构的总质量,只有当填充长度大于有效填充长度时,泡沫铝提高铝管承载能力的作用才能充分发挥;部分填充管对空铝管的弯曲载荷相对提高量随铝管壁厚减小而增大。

| Abstract: | The bending property of aluminum tubes partially filled with aluminum-foam was studied in the three-point bending experiment.The results indicate that the bending load and absorbed energy of partially foam-filled tube significantly increase and the deformation mode changes from single-fold model to multi-fold model when compared with empty tube.The bending carrying capacity and energy absorption capacity of partially foam-filled tube increase with the decrease of aluminum foam porosity,but the displacement ... |
