Parametric Analysis of the Impact Level of Tank Truck Columns on Transport Facilities during Braking

Systemic numerical studies have been carried out to analyze the influence of the main traffic parameters at the moment of braking of a regular column of tank trucks in order to determine the maximum values of the dynamic impact on transport facilities. A refined design scheme of a unified oscillatory system, a mathematical model developed by the authors, and a unified numerical algorithm for nonlinear oscillations are used. The computer complex in the Simulink simulation package for dynamic and event-driven systems of the MATLAB system was adapted to solve the posed problem on the basis of expert models developed earlier by the authors. A parametric analysis of the impact level of tank truck columns on transport facilities when changing the mode of movement is carried out according to the results of computational experiments. When simulating the passage of a vehicle column, the parameters of the movement of the column, the position of the first vehicle on the transport facility at the time of the start of braking, as well as the characteristics of an individual tanker in the column were varied. The degree of influence of each parameter is determined, and their combinations in which there is a danger of excess dynamic impact of a moving load on transport facilities are identified. The expediency of separating such columns into a special class of moving load and the need to amend the regulatory documents are shown.
