摘　　要：为有效提升营运车辆安全性能,中华人民共和国交通运输部于2018年2月26日发布行业标准《营运货车安全技术条件第1部分:载货汽车》(JT/T 1178.1-2018),标准中第6.4项要求营运货车驾驶室应具备乘员保护功能。本文以标准中附录C《驾驶室结构强度试验方法和生存空间检验用人体模型要求》中顶部强度试验为基础,对同一系列平后围与凸后围两种不同样式驾驶室强度的仿真评价研究,评价分析两种后围样式驾驶室在模拟车辆侧翻后驾驶室顶部朝下的事故形态下,实际的生存空间情况。In order to improve the safety performance of commercial vehicles effectively,the Ministry of Transport of PRC issued the transportation industry standard JT/T 1178.1-2018"Safety specification for commercial vehicle for cargos transportation–Part 1:Goods vehicle"on February 26,2018.This standard requires that the cab of commercial trucks should have the occupant protection function in section 6.4.Based on the roof strength experiment in Appendix C“The cab structure strength test method and manikin to be used to verify the survival space”,this paper carried out simulation of the roof strength of flat rear wall and convex rear wall which the cab are the same series,and analyzed the condition of the actual survival space during the simulation accident with the cab facing the ground after the vehicle rolls over.

关 键 词：营运货车 驾驶室 顶部强度 生存空间
