吸能盒盒体内部结构的改进

Internal Structure Improvement of Box Body of Can Suck Box

为了使汽车在碰撞过程中吸收更多的能量,降低车辆及其部件的损坏程度,按照吸能盒的设计原则,对某型车辆吸能盒盒体的内部结构进行优化设计,并利用LS-DYNA进行了碰撞模拟仿真。在此基础上,通过分析该吸能盒吸能性的评价标准,将原车吸能盒与改进的吸能盒的吸能特性进行对比分析。结果表明:具有内部蜂窝孔结构的吸能盒的抗撞性比原结构的吸能盒有较大提高。

In order to make the car to absorb more energy damage extent as far as possible and to reduce the damage in the process of collision, to reduce the of the vehicles and other components, according to the energy absorption box design principle, the box body internal structure of the energy absorption of suction box of a car was optimized designed, and collision simulation was studied by using LS-DYNA. On this basis, through the analysis of energy absorption box endergonic evaluation stand- ard, the original box and the improvement of energy absorption box car energy absorption of energy absorption characteristics were analyzed. The results show that the internal structure of honeycomb holes can suck box impact improves a lot than the orizinal structure of the suction can box.
