摘要：Since most of the heavy-duty lorry rear underrun protective device does not have sufficient blocking capacity to prevent drilling collisions, the casualty rate of small passenger vehicle colliding with heavy trucks is high. Based on the actual participation in road traffic accident identification work, the authors investigated the current installation status and common problems of the rear underrun protective device of heavy-duty lorry. According to the requirements of GB 11567-2017, the authors used LS-DYNA simulation software for a brand of heavy-duty warehouse-type semi-trailers. The mechanical performance model of the rear underrun protective device is studied to provide safety for road traffic and to avoid or reduce the casualties caused by a vicious rear-end collision.
