The work is devoted to the issues of finite element modeling of mobile frontal barriers (MFB, truck mounted attenuators, mobile crash cushions), based on computer simulation of digital modeling of the behavior of elements in the MFB system, which includes a cover truck and a test vehicle designed to ensure the safety of road workers, when they are hit by cars in places of works on public roads that require temporary changes in the organization of traffic. It discusses various designs of trailer MFBs, the basic principles of damping devices, and defines the criteria for developing structures, based on digital mathematic modeling by the finite element method (FEM).
