摘　　要：为分析粘接式侧窗玻璃对客车侧翻性能的影响,提出了一种简化的粘接式侧窗玻璃模型。基于钢化玻璃破坏应力在静态作用下较小的准则,应用试验方法,对粘接式侧窗玻璃进行准静态加载。在试验中提取玻璃上6个应力提取点的应力,对其平均应力进行曲线拟合,确定钢化玻璃的失效断裂极限。将玻璃断裂极限应用于有、无侧窗玻璃两种侧翻模型,对两种模型进行对比分析,结果表明粘接式侧窗玻璃对车侧翻性能影响较小。A simplified model of the side window bounding system of a bus is proposed in order to study the impact of the bounding system on the bus rollover safety.Based on the fact that under static load the failure stress of tempered glass is small,experiments are carried out,in which quasi-static load is applied on the tempered glass.During the experiment,the stress values at six points on the glass are collected.Then by fitting the mean-stress of the six points,the breaking limit of the tempered glass is obtained.Finally the breaking limit is applied to two bus rollover models,one with and the other one without adhesive glass,to compare their rollover performance.Results show that the adhesive side window does not have significant impact on the bus rollover process.
