摘　　要：为验证一款低顶驾驶室的顶部强度和生存空间是否满足GB 26512—2011《商用车驾驶室乘员保护》法规的要求,建立了相应的有限元模型和假人模型,并按该标准的规定进行了顶部强度的试验仿真分析,获得了驾驶室变形情况和驾驶员生存空间变化情况,并与实车试验结果进行了对比。结果表明:该低顶驾驶室强度能够满足GB 26512—2011顶部强度试验要求并能够保证驾驶员的生存空间要求,且仿真结果与实车试验结果符合良好。To verify the strength and survival space of a low-top truck cab meeting the requirement of roof strength test according to GB 26512—2011（The protection of the occupants of the cab of a commercial vehicle） or not,cabin finite element model were created for numerical simulation with a manikin added on the driver seat.Roof strength test was numerical investigated according to GB 26512—2011.Deformation of the cab and variation of survival space were obtained and compared with real vehicle test results.The numerical results show that the low-top cab can satisfy the demands of roof strength test of GB 26512—2011 and the survival space is sufficient for the safety of driver or front seat passenger,numerical results and real vehicle test results agree well with each other.
