建立了详细的轨道车辆司机室内部结构有限元模型,采用欧盟资助项目SAFEINTERIORS中所推荐的碰撞冲击脉冲作为输入,参考ATOC AV/ST 9001标准对司乘人员损伤程度进行评定,引用被国际上广泛采用的HybridⅢ50百分位成年假人,对机车司机室的正、副司机进行损伤分析。研究结果表明:司机室操纵台的强刚度、弱吸能性能对司机人身的生命安全威胁极大,正、副司机的胸部变形量都超过了最大容许值;同等条件下,正司机的左、右股骨损伤指标和胫骨指数明显超过了各自的极限值,其损伤程度远远高于副司机。
A detailed finite element model of the internal structure of the driver’s cab of a rail vehicle is established. The impact shock pulses recommended by the SAFEINTERIORS funded by the EU are used as inputs. The damage degree of passenger and crew members is evaluated with reference to the ATOC AV / ST 9001 standard. HybridIII50 percentile adult dummy, the locomotive cab of positive and deputy drivers for damage analysis. The results show that the strong stiffness and weak energy absorption of the console of the driver’s cab have a great threat to the driver’s life safety. The chest deformation of both the driver and the driver exceed the maximum allowable value. Under the same conditions, Right femoral injury index and tibia index significantly exceed their respective limits, the degree of damage is much higher than the deputy driver.
