The article deals the method of calculation studies of impact tests of tank containers to confirm the ability of portable tanks and multi-element gas containers to withstand the impact in the longitudinal direction on a specially equipped stand accredited in the certification system of the Register of Shipping of Ukraine, or using a railway platform and executing an impact force generated by a wagon-striker in accordance with the requirements of the UN Register of Shipping. It is shown that the main estimated characteristic of the UN requirements is the impact response spectrum (accelerations) for the interval natural frequencies of the impact impulse. The calculation of the points of the impact response spectrum curve according to the test results is shown in four stages. The test configuration of a railway platform with a tank-container for impact loads is presented, in which the impact is performed in such a way that the curve of the impact response spectrum obtained during the tests of both fittings under a single impact repeated or exceeded the minimum impact response curve spectrum at all frequencies in the range from 2 Hz to 100 Hz. The matrices of relative displacements and accelerations for the interval natural frequencies of the impact wave are given. The results of the research are presented in graphical form, which shows that the experimental values of the impact response spectrum exceed the minimum allowable values. The equation of the experimental curve of the shock response spectrum in the frequency range 0-100 Hz is described by the power dependence; the coefficients of the equation were determined by the statistical method of the maximum likelihood, with the determination factor being 0.897, which is a satisfactory value. The comparative analysis showed that the experimental curve of the impact response spectrum in the frequency range 0-100 Hz exceeds the normalized curve, which confirms compliance with regulatory requirements. It is proposed to use a new test configuration using a tank car with bulk liquid, where the processes occurring under impact significantly differ from other freight cars subjected to longitudinal impact loads of the tank container. The hydraulic shock caused by the impact on the tank container and the platform creates a turning moment, which causes the rear fittings to be unloaded.

This article deals with the method of computer-aided studies of the results of tank container impact tests to confirm the ability of portable tanks and multi-element gas containers to withstand the impact in the longitudinal direction on a specially equipped test rig or using a railway flat car by impacting a flat car with a striking car, in compliance with the requirements of the UN Navigation Rules and Regulations. It is shown that the main assessed characteristic of the UN requirements is the spectrum of the shock response (accelerations) for the interval natural frequencies of the shock pulse. The calculation of the points of the shock response spectrum curve based on the test results is reproduced in four stages. A test configuration of the impact testing of the railway flat car with a tank container is presented, and the impact is performed in such a way that, under a single impact, the shock spectrum curve obtained during the tests for both fittings subjected to impact repeats or exceeds the minimum shock spectrum curve for all frequencies in the range of 2 Hz to 100 Hz. Formulas for determining the relative displacements and accelerations for the interval natural frequencies of the shock wave are given. The research results are presented in graphical form, indicating that the experimental values of the shock response spectrum exceed the minimum permissible values; the equation of the experimental curve of the shock response spectrum in the frequency range 0–100 Hz is described by power-law dependence. The coefficients of the equation were determined by the statistical method of maximum likelihood with the determination factor being 0.897, which is a satisfactory value; a comparative analysis showed that the experimental curve of the impact response spectrum in the frequency range 0–100 Hz exceeds the normalized curve, which confirms compliance with regulatory requirements. A new test configuration is proposed using a tank car with a bulk liquid, the processes in which upon impact differ significantly from other freight wagons under longitudinal impact loads of the tank container. The hydraulic impact resulting from the impact on the tank container and the platform creates an overturning moment that causes the rear fittings to be unloaded.

The paper presents the assessment of the fat – and-oil industry of Ukraine. Leaders of the largest producers of sunflower oil in Ukraine were determined in percentage terms; they are LLC "European Transport Stevedoring Company" (6.6% of total production), LLC Optimus Agro Trade (6.1%), LLC Pridneprovsky SEZ, Ltd (4.7%) and PJSC "Vinnitsa OZHK" (4.7%). The development of oil and fat enterprises of Ukraine was analyzed and the main problems were identified, which include the choice of transportation means of vegetable oils from factories to the seaport and the territorial location of factories producing vegetable oils. It is established that at present the currently relevant type of transportation of bulk cargo has become tank containers, as transportation in them is carried out without intermediate overflow of the product when changing the mode of transport, which ensures the increased safety of transportation and cargo, as well as contributing to the environmental security during the transportation process. The article includes the classification of tank containers and identification of the main world manufacturers of chemical and food tank containers. It is determined that the construction of the tank container should withstand the action of its own forces of inertia, which occur during the movement of the vehicle, as well as under impact of wagons that occur during shunting operations, including gravity marshalling yard, emergency braking and other emergencies that may occur during operation under the following accelerations: in the longitudinal direction Pпр it is 2 g; in transverse direction Pп it is 1 g; in the vertical direction Pв it is 2 g; under impact: for a loaded container with dangerous goods the acceleration is 4 g; for a loaded container with a safe cargo it is 2 g; for an empty container (to check the fittings) it is 5 g. The paper describes the procedure for obtaining dynamic characteristics of a tank-container for transporting vegetable oils placed on a platform car under impact tests. The presented example of obtaining the values of accelerations that act on the load-bearing structure of the tank-container under impact shows that the designed construction of the tank-container meets the regulatory requirements for strength characteristics.
