摘要:
为提高薄壁吸能管的耐撞性,该文设计了一种复合材料仿竹薄壁管。将钢材、铝材及复合材料运用于仿竹薄壁管,利用有限元法模拟薄壁管的轴向碰撞,对比分析了三类材料薄壁管的耐撞吸能效果,得出玻璃纤维/环氧树脂基复合材料仿竹薄壁管耐撞吸能效果最佳。为进一步提高薄壁管的耐撞性和可靠性,将试验设计、响应面模型、可靠性理论和优化算法相结合,求出仿竹薄壁管的最优结构。研究表明,仿生设计、复合材料运用、可靠性理论及优化算法相结合的研究方法可提高薄壁管的耐撞性能。
Abstract:
In order to improve the crashworthiness of the thin-walled energy absorption tube,the bamboo-like thin-walled tubes with steel,aluminum and composite materials incorporated are designed.The finite element method is adopted to simulate the axial impact of the bamboo-like thin-walled tube for analyzing the energy absorption effect of the three kinds of material tubes when the collision happens.The result shows that the glass fiber/epoxy resin composite material bamboo-like thin-walled tube is the best for energy absorption.To improve the crashworthiness and the reliability of the thin-walled tube,the design of experiments,the response surface model,the reliability theory,and the optimization algorithm are combined to obtain the optimum structure of the bamboo-like thin-walled tube.The results show that the method combining the bionic design,the composite material,the comprehensive reliability theory and the optimization algorithm is useful for improving the crashworthiness of the thin-walled tube.
