摘要

为了提升轻型汽车的碰撞安全性,建立了某轻型卡车有限元模型,对驾驶室进行有限元仿真模态以及100％正面碰撞仿真,并通过驾驶室试验模态与实车碰撞试验,验证有限元模型的准确性．参照ECE R29-03标准,针对最大允许质量小于7 500kg的轻型卡车,提出了正面A柱摆锤撞击仿真方法．同时根据该车碰撞仿真结果,发现驾驶室压溃损坏,A柱及后围变形严重,假人触碰驾驶室内非弹性零件,乘员生存空间不满足要求．为提升碰撞性能,采取了A柱填充结构泡沫、增加后围加强梁和后围横梁加强板等改进措施．结果表明:驾驶室刚度得到提升,优化了力的传递路径,各零件能量吸收更均匀,具有足够的生存空间,顺利通过正面A柱摆锤撞击试验．

Abstract

To improve the crashworthiness of light truck, the finite element model of a light truck was established. Cab modal analysis and vehicle 100% frontal collision simulations were carried out. The test and simulation results were compared to verify the finite element model. According to ECE R29-03 standard, the simulation methods of A-pillar impact test were proposed for a light truck with gross mass less than 7 500 kg. According to the simulation results, the cab was crushed, and the A-pillar and the rear wall were severely deformed. The non-resilient parts were contacted with manikin, and the living space could not satisfy the requirements. To enhance the collision performance, some improvement mea-sures with filling structural foam in A-pillar and adding rear wall reinforcing plate and beam were applied. The simulation results show that the cab stiffness is promoted with optimized transfer path of force, and the energy absorption becomes more homogeneous without penetration into survival space.
