摘　　要：应用有限元与多刚体方法,针对某ZL50型装载机沿30°和45°斜坡翻车过程中司机动态响应进行仿真分析。以人体损伤为评价指标对比分析了不同的翻车保护结构(ROPS)刚度、斜坡角度以及安全带约束方式对司机损伤的影响。结果表明:在能够提供人体生存空间的前提下,ROPS刚度越小,人体受到的损伤越小;斜坡角度的变化影响人体损伤部位;4点式安全带能够有效降低人体头部损伤的几率;安全带形式对颈部损伤影响很小。The dynamic responses of the driver in a ZL50 loader during rollover process on 30°and 45° slopes were studied using the finite element analysis and the multi-rigidbody method.The effects of the stiffness of the rollover prevention structure（ROPS） ,the slope gradient,and the seat-belt restraint on driver injury were analyzed taking the human body injury risks as evaluation indexes.The results showed that on the premise of maintaining a necessary survival space for the driver,the human body injury alleviates with decrease of ROPS stiffness.The change of slope gradient leads to the various injury position of human body.The 4-point seat-belt decreases effectively the head injury risk,but the type of seat-belt has little impact on neck injury.
