本文对我国在用汽车中市场占有率较高的有车架的轻型汽车的碰撞安全性进行了理论分析及模拟计算,提出了汽车在前部碰撞时沿宽度方向单位长度的吸收能量分布(即能量密度 q)理论为:以车架两个纵梁为中心的截头尾的双正态分布。
In this paper, the theoretical analysis and simulation of the collision safety of a light vehicle with a high market share in a car market in China are presented. The absorption energy distribution per unit length along the width direction of a vehicle in a frontal collision is proposed Energy density q) The theory is: bimodal distribution of the truncated tail centering on two longitudinal beams of the frame.
