【摘要】:為得到具有良好耐撞性能的緩沖結(jié)構(gòu),提升車輛在碰撞中的安全性,以蜂窩鋁為研究對象,建立了有限元模型,研究了不同壁厚參數(shù)的正六邊形鋁蜂窩結(jié)構(gòu)的吸能特性,并進一步分析了截面尺寸對緩沖結(jié)構(gòu)碰撞特性的影響,最終結(jié)合實際應(yīng)用,給出了性能合格的緩沖結(jié)構(gòu)方案。通過等效的臺車測試,試驗和仿真結(jié)果的基本一致,驗證了有限元模型的正確性。研究結(jié)果表明,蜂窩鋁緩沖結(jié)構(gòu)能有效吸收車輛的碰撞動能,并降低碰撞過程中車輛的最大減速度,研究對車輛緩沖結(jié)構(gòu)及其參數(shù)的選定有重要的參考意義。
[Abstract]:In order to obtain a buffer structure with good crashworthiness and enhance the safety of vehicles during collision, a finite element model was established to study the energy absorption characteristics of hexagonal aluminum honeycomb structures with different wall thickness parameters. Furthermore, the effect of section size on the impact characteristics of buffer structure is analyzed. Finally, the scheme of buffer structure with qualified performance is given in combination with practical application. The validity of the finite element model is verified by the equivalent test and simulation results. The results show that the honeycomb aluminum buffer structure can effectively absorb the collision kinetic energy of the vehicle and reduce the maximum deceleration speed of the vehicle during the collision process. The study has important reference significance for the selection of the vehicle buffer structure and its parameters.
