The paper presents the strength analysis results for a tank-container designed for liquid cargo transportation by rail, automobile and water transport based on computer modeling.The most severe in terms of loads and extreme operation mode of tank-containers is chosen as the conditions for the computer experiment, implying an impact in the longitudinal direction when railway cars collide berkley power worm 100 pack during their dismantling from the hill at marshalling stations.Calculations are performed using the static analysis module Static Structural of the ANSYS Workbench engineering software package for two loading options for a transport tank: a standard one, corresponding to GOST 33211-2014, and a refined loading option for the tank-container shell.
Based on the numerical solution of the differential equations system for the liquid cargo movement, the analysis of which is performed using the finite volume method in the CFX module of the ANSYS Workbench engineering software package, the obtained values of hydrodynamic pressures in the tank are accepted as the initial data for the refined computer simulation.Conclusions are drawn on the influence of taking into account the distribution of hydrodynamic pressure inside the transport tank on the stress-strain state of the tank-container.The distributions of normal, equivalent von Mises stresses, as well as deva curl arc angel deformations for two loading schemes are obtained.
Using the Fatigue Tool of the Static Structural static analysis module, the number of cycles that the structure can withstand is determined, taking into account the equivalent stresses concentration areas.The conclusions are formulated based on the computational results, and the recommendations are offered to improve transportation safety and ensure the safety of cargo using tank-containers.
