一种基于碰撞重现技术的新型头部碰撞损伤试验系统
A Novel Experimental System Used for Head Injury Study Based on Reconstruction Technology of Pedestrian-vehicle Collision
摘要
Abstract
In allusion to the difficulties of carrying out highly reliable injury testing studies for pedestrian-vehicle collisions,this paper proposes an experimental system for measurements of head injuries based on reconstruction technol ogy of collisions.Together with a multi-functional collision board,a chain-drive mechanism and a slide lump mechanism are jointed to construct a device for collision simulation.A crash-test dummy is embedded into the slide lump mechanism,and therefore creates a testing model with adjustable weights.Based on a force-sensing module integrated in the testing model,a data acquisition and analysis module is designed to realize real-time analyses of head injuries.In order to guarantee the precision of the collision experiment,finite element analyses are used to optimize structure of this experimental system.This paper has provided a testing method for head injury studies during pedestrian-vehicle collisions with high-reliability and low-cost.关键词
