摘　　要：装载机驾驶室上的翻车保护结构(ROPS)是针对车辆倾翻时发生连续翻滚而设计的安全保护装置,ROPS的可靠性对司机的生命安全有着不可忽视的作用。建立某型装载机驾驶室ROPS虚拟样机,根据非线性有限元接触理论,对ROPS进行最小侧向承载能力、侧向最小能量吸收能力和最小纵向承载能力有限元分析,分析结果满足国际标准对ROPS性能的要求。在试验室对该型ROPS实体进行试验测试,试验结果和仿真结果基本吻合,验证了理论研究的正确性。相关研究可为装载机ROPS的优化设计提供有效依据,对于提高装载机作业时的安全性具有重要意义。ROPS for loaders is a safety protection device to encounter continuous roll-over of vehicles,which reliability is assignable to life of the operator.A virtual machine has been constructed for a loader's ROPS over the cab,and then finite element analyses are done on the ROPS of its min side load capability,min side load absorption capability,and min longitudinal load capability according to a non-linear contact theory of finite element,which results show satisfaction with the ISO requirements of ROPS functions.Besides,lab ROPS test results meet basically with those of actual tests,thus verifying correctness of the theoretical study.Relevant studies of the project as an effective reference can be provided to optimal design of ROPS for loaders and have importance to upgrade the loader's safety operation.
