不同重叠率下两车正面碰撞兼容性研究

A Study on Compatibility of Vehicle-to-Vehicle Frontal Crash in Different Overlap Ratios

本文以小型轿车与中型轿车、MPV、SUV、皮卡四种不同车型在不同重叠率下的正面碰撞有限元仿真为基础,选取小型轿车的前围板及A柱侵入量和乘员舱加速度作为衡量兼容性的参数,对不同车型与小型轿车在不同碰撞重叠率下的正面碰撞兼容性进行了研究,探究不同碰撞重叠率下影响正面碰撞兼容性的关键因素,为整车设计提供理论依据。

Based on small cars and midsize sedan, MPV and SUV, pickup truck, four different models under different rate of overlapping of frontal crash simulation based on finite element, select small car dash panel and A column into amount and crew capsule acceleration as to measure the parameters of the compatibility, the different models under different collision overlap rate with small cars in the frontal crash of compatibility was studied, under different collision overlap rate to explore the key factors influencing the frontal crash compatibility, as to provide theoretical basis for the vehicle design.
