摘要:
为研究某型低地板列车的吸能防爬装置的吸能防爬特性,提高车体结构的正面耐碰撞性,运用非线性瞬态动力学软件LS-DYNA 对其进行数值仿真,得到膨胀式吸能构件的吸能特性;然后在该吸能装置上增设导向杆,并研究了壁厚、诱导孔等几何参数对该吸能管碰撞特性的影响;最后结合该型低地板列车做碰撞仿真分析。结果表明,增设导向杆和诱导孔后的吸能防爬装置具有良好的吸能与防爬能力;壁厚能显著影响吸能管的碰撞界面力和吸收的能量,壁厚越大,碰撞界面力和吸收的能量越大。证明该吸能防爬装置符合设计要求,为吸能防爬装置在低地板列车上的合理应用提供理论指导。
Abstract:
To study the energy absorption and anti-climbing properties of the anti-climbing energy absorbing device based on a low-floor vehicles and improve the frontal crashworthiness of car body structure, the numerical simulation was carried out using the nonlinear transient dynamic software LS-DYNA to obtain the energy absorption properties of the expanded energy absorbing component; Then the guide rod was added on the energy absorbing device, and the influence of the geometrical parameters, such as the thickness of the wall and the induced hole on the collision properties of the energy absorbing tube were studied; Finally, combined with the low floor vehicle, the collision simulation analysis was carried out. The results showed that the anti-climbing energy absorbing device with the guide rod and the induced hole has good energy absorption and anti-climbing ability; Wall thickness has a significant influence on the interfacial force and energy absorbed, the larger the wall thickness is, the larger the collision force and absorbed energy are; It is proved that the energy absorbing device can meet the design requirements, and can provide theoretical guidance for the reasonable application of the anti-climbing energy absorbing device on the low-floor vehicle.
