An automobile front longitudinal beam filled with a negative poisson ratio honeycomb material comprises a front longitudinal beam shell, a cavity in the front longitudinal beam shell is filled with the negative poisson ratio honeycomb structure material, and the negative poisson ratio honeycomb structure material is connected with the front longitudinal beam shell to form a plurality of cell elements in a surrounding mode. By means of the structure, the mechanical performances of the automobile front longitudinal beam can be improved, then the energy absorption effect of the automobile front longitudinal beam is improved, the automobile front longitudinal beam can well adapt to impact at a high speed and a low speed, deformation of the front longitudinal beam can be well induced when the front longitudinal beam is impacted, and performances are reliable.

    本发明提出一种负泊松比蜂窝材料填充的汽车前纵梁,包括前纵梁壳体,前纵梁壳体内部空腔填充负泊松比蜂窝结构材料,负泊松比蜂窝结构材料与前纵梁壳体连接,围设成多个胞元。本发明结构的设置可以提高汽车前纵梁的机械性能,进而提高其吸能效果,能很好地适应高速与低速时的冲击,并能很好地诱导前纵梁在受到冲击时的变形,性能可靠。
