摘要:

用试验研究了碳纤维 -环氧树脂圆弧型波纹梁在轴向准静态载荷下的损毁过程、峰值载荷和能量吸收能力。通过 3组不同尺寸的波纹梁在轴向准静态载荷下的压缩试验,研究了波纹梁的缓冲吸能机理,并对波纹梁的峰值载荷和吸能能力做了定量分析,讨论了不同结构尺寸对波纹梁在轴向准静态载荷下的峰值载荷和吸能能力的影响。

Abstract:

The crushing process, peak load and energy absorption property of carbon epoxy circular waved beams under quasi static loading are investigated experimentally in this paper. Three sets of waved beams with different sizes are tested under compressive loads to failure. Based on the experimental data, the energy absorbing mechanism of the composite waved beams is studied. The peak loads and energy absorbing property are analyzed quantitatively. And the size effect on the peak load and the energy absorbing property is discussed.

Key words: composite material, waved beams, energy absorption, peak load
