安全带对列车驾驶员的碰撞损伤防护研究
Study on the prevention effect of seatbelt for the train driver collision injury
摘要
Abstract
The simulation of the train crashing with the rigid wall was carried out with the driver under no seatbelt, two-point belt and three-point seatbelt restraint using the nonlinear explicit dynamic method with respect to the secondary collision on the rail train driver injuries. Several part injuries of the train driver body were analyzed and compared under the three conditions. The results show that under the condition of no seatbelt restraint, the driver is separated from the chair finally. Injuries on head and chest meet the standard and injuries on neck are close to the criterion values, while injuries on lower limbs are beyond the criterion values. Under the condition of two-point belt restraint, the driver is not separated from the chair. Injuries on neck and lower limps decrease, but injuries on head and chest increase and the abdomen force is beyond the criterion value. The three-point seatbelt restrains the driver on the chair and injuries on head, neck and chest decrease by more than 20%. The tibia index decreases by 63.2% and the femur force decreases by 90%. According to the calculation results, three-point seatbelt plays a better role in injury prevention for the train driver.关键词
