Abstract

Vibrator, as a crucial vehicle of oil and gas exploration, is challenged by the complex terrains. The probability of rollover accident is therefore high in bumpy terrain in which the drivers' life is seriously threatened. Finite element numerical analysis was used to study the injury of the driver's head, neck and chest in the rollover accidents of domestic KZ-28 type vibrator on different conditions. The injuries of three parts were evaluated based on the human injury criteria. Driver's safety on different rollover conditions was comparatively analyzed. The results indicated that the injury degree of human head caused by vibrator rollover accident is at a low level. In comparison with head, the human neck is more likely to be injured than head and chest. In three different rollover accidents, the injury degree of drivers on the rollover condition of the vibrator colliding with slope multiply is most serious. Besides, the results demonstrated that the safety of driver can be enhanced by the rollover protective structures of KZ-28 type vibrator. This structure requires to be improved in energy absorption and isolation buffer. In addition, the safety belt and collision angle between the cab and the ground are also significantly associated with the injury degree. This research is of guiding significance to vibrator driver for taking safety protection measures.
