室内停车场防撞带设计的碰撞仿真分析

针对室内停车场碰撞事故的伤害问题,提出了停车场防撞带的设计,建立有无防撞带的车辆碰撞模型,并对长方体防撞带与波浪形防撞带进行性能分析比较,运用LS-DYNA软件对车辆、防撞带以及墙体碰撞进行仿真模拟。得到防撞带和车辆翼子板的等效应力分布和能量转化情况,证实了防撞带能有效减少车辆的损害程度,且长方体防撞带效果更好。

Collision Simulation Analysis of Indoor Parking Anti-collision Belt Design

Aiming at indoor parking collision damages, this paper proposes the design of anti-collision belt and establishes vehicle collision model with or no anti-collision belt. The rectangular anticollision belt and wavy anti-collision belt performances are analyzed through LS-DYNA for simulation of vehicle collision into the wall body.The results demonstrate the equivalent stress distribution and energy conversion of anti-collision belt and the vehicle fender, which confirms that the anti-collision belt can effectively reduce vehicle damage degree and the effect of the rectangular anti-collision belt is better.
