某客车侧翻安全性吸能结构的设计

摘要

Based on the analysis on bus rollover process, a novel energy-absorbing structure of a mono-coque bus is proposed for rollover buffering. The analysis models for the closed-loop body segments with both original and modified structures are built respectively, on which the simulations are conducted. The results show that all evaluation indicators for rollover safety of modified structure are better than that of original structure and hence the rollover safety of body structures is improved and the life safety of occupants is effectively assured.%基于对客车侧翻过程的分析,为某款全承载客车提出了一种新型的侧翻缓冲吸能结构,分别建立了其原结构与改进结构的车身段封闭环侧翻分析模型,并进行仿真.结果表明,改进后结构各侧翻安全性评价指标均较原结构有所改善,车身结构侧翻安全性得到加强,有效地保证了乘员的生命安全.
