摘　　要：为了提升轻型卡车的碰撞安全性,建立了某轻型卡车有限元模型,进行了驾驶室模态仿真以及100%正面碰撞仿真,并通过驾驶室模态试验与实车碰撞试验,验证了有限元模型的准确性。参照ECE R29-03法规进行了侧面20°摆锤撞击仿真,并通过侧围顶部填充结构泡沫、增加顶部横梁和后围加强梁等措施对原设计驾驶室进行改进。结果表明:改进后驾驶室刚度得到提升,各部件能量吸收较均匀,生存空间最小尺寸由75.3mm增加为121.9mm,加强了对乘员的保护。In order to enhance the crashworthiness of a light truck, the light truck finite element model was built. The cab modal simulation and truck 100% frontal collision simulation were carried out. The cab modal tests and actual collision tests verified the accuracy of the finite element model. With the ECE R29-03 regulation as reference, side 20° pendulum impact simulation was carried out. Some improvement measures, such as filling structural foam in side panel top, adding a roof crossbeam and rear wall reinforcing beam, had been used to improve the original cab. The results show that the cab stiffness is improved, the energy absorptions of parts are more homogeneous, and the minimum survival space is increased from 75. 3 mm to 121. 9 mm,so the protection of the occupants is enhanced.
