某新能源商用车正面中心柱碰仿真分析研究

Simulation and Analysis of Frontal Center Column Collision of a New Energy Commercial Vehicle

摘要: 为解决能源危机和环境污染等问题，新能源汽车已经逐步进入到大众的视野中。随着其保有量的逐年增加，人们对新能源汽车的安全性也越来越关注。为改善某款新能源商用车在行驶过程中的安全性，以Hypermesh为前置处理，在LS-DYNA中对其进行30 Km/h正面中心柱碰工况(30FCP)仿真研究，并通过实车试验对其进行损伤分析。实车试验结果表明：试验后，车辆气囊点爆，两侧车门能够正常打开，蓄电池完好，仪表板Ready灯熄灭，高压下电。

Abstract: In order to solve the problems of energy crisis and environmental pollution, new energy vehicles have gradually entered the public view. With the increase of its possession year by year, people pay more and more attention to the safety of new energy vehicles. In order to improve the safety of a new energy commercial vehicle during driving, Hypermesh was used as the pre-treatment to carry out a simulation study on 30 Km/h frontal center pillar impact condition (30FCP) in LS-DYNA, and the damage analysis was carried out through vehicle test. The actual vehicle test results show that after the test, the airbag of the vehicle is ignited, the doors on both sides can be opened normally, the battery is in good condition, the Ready lamp on the dashboard is off, and the power is off under high voltage.
