Abstract

In this study, the effect of fiber angle alignment on the energy-absorbing behavior of 0°, 5° and 10° conical CFRP tubes was numerically investigated. Feedforward Neural Networks (FFNN) were used to determine the optimum fiber angle alignment for the highest absorbed energy (AE), crash force efficiency (CFE), and lowest peak force. In addition, 100, 400, 600, and 800 kg/m3 metallic foam filling was used to investigate the foam filling effect in tubes with an optimum fiber angle alignment. The results showed that the amount of absorbed energy can increase by up to 118% with optimum fiber alignment.

纤维角度排列对锥形复合管吸能行为的影响

摘要

在这项研究中，纤维角度排列对 0°、5° 和 10° 锥形 CFRP 管的能量吸收行为的影响进行了数值研究。前馈神经网络 (FFNN) 用于确定最高吸收能量 (AE)、碰撞力效率 (CFE) 和最低峰值力的最佳纤维角度对齐。此外，使用 100、400、600 和 800 kg/m3 金属泡沫填充物来研究具有最佳纤维角度排列的管中的泡沫填充效果。结果表明，采用最佳纤维排列，吸收的能量最多可增加 118%。
