12m大客车侧面碰撞安全性分析

Side impact satety analysis of 12m large bus

建立了被撞大客车车身骨架、撞击大客车车身骨架和撞击货车有限元模型，运用ANSYS／LS—DYNA软件，分别模拟了撞击大客车与被撞大客车和撞击货车与被撞大客车侧面碰撞．并从侧面碰撞位置、骨架结构变形、乘员生存空间、碰撞速度和加速度方面分析了被撞大客车侧面碰撞安全性。

It sets up a finite model of impacted large bus body framework,impacts large bus body framework and impact truck,using ANSYS/LS-DYNA software, separately simulates the side impact between impact large bus and impacted large bus,impact truck and impacted large bus,and analyses the safe capability of impacted large bus from side impact position,framework struction deformation,passenger live space, impact speed and accelerate etc.
