【摘要】 采用先进粉末冶金发泡法（advanced powder compact melting,APCM）制备了不同直径的泡沫铝元件，并将其按不同粘接方式无序填充到铝合金薄壁管中，获得了不同类型的APCM泡沫铝填充薄壁管复合结构（简称“填充管”）。通过万能试验机对填充管进行准静态压缩试验，研究了填充元件直径和粘接方式对填充管力学性能及吸能效果的影响。结果表明，粘接方式对填充管性能的影响要比填充元件直径更为显著。同种粘接方式下，填充泡沫元件直径为15 mm的填充管压缩吸能效果最好；不同粘接方式下，发泡粘接填充管的压缩吸能效果最优，而粘接填充管的压缩吸能效果要优于不粘接填充管。更多还原

【Abstract】 The aluminum foam elements in different diameter were prepared by advanced powder compact melting method(APCM), which were filled into the aluminum alloy thin-walled tubes with different bonding methods disorderly, and finally the thinwalled tubes filled by APCM aluminum foams in composite structure were obtained(as called the filled tubes). The quasi-static compression test of the filled tubes was carried out by universal testing machine, and the effects of filling element diameter and bonding method on the mechanical properties and energy-absorbing effect of the filled tubes were investigated. The results show that the bonding method has more significant effect on the performance of the filled tubes than that of the filling element diameter. With the same bonding method, the compression energy absorption effect of the filled tubes with filling element diameter of 15 mm is the best.With the different bonding methods, the compression energy absorption effect of the foam bonded filled tubes is the best, while the compression energy absorption effect of the bonded filled tubes is better than that of the non-bonded filled tubes.更多还原
