摘　　要：针对校车侧翻后出现车身骨架变形侵入乘员生存空间的问题,对校车前部侧窗立柱处骨架进行加厚处理,通过试验和LS-DYNA软件分析了校车改进后车身结构的变形特征和安全性能.结果表明:改进后的车架最大变形量发生在侧窗立柱处,最大位移达114.1mm,侧翻后立柱与生存空间之间的最小间隙为30mm,与改进前相比安全性能有较大提升.Aiming at the problem that the body skeleton deformation intrudes into the occupant living space after the rollover of the school bus,the skeleton of the front side of the school bus is thickened,and the deformation characteristics of the improved school vehicle body structure are analyzed by LS-DYNA software and safety performance.The results show that the maximum deformation of the improved frame occurs at the side window column with the maximum displacement of 114.1mm.The minimum clearance between the rear column and the living space is 30 mm.The improvement provides a reference for the further optimization of the body frame of the school bus.
