Abstract

As a result of the aggression of the Russian Federation in 2014, as well as the large-scale invasion in February 2022, Ukraine became the most explosive contaminated country in the world. The relevance of the issue of reconnaissance and demining of the area from explosive devices both during and in the absence of combat operations has increased many times over. The experience of war shows that the enemy, despite international conventions banning certain types of mine weapons, uses its entire arsenal of mines and improvised explosive devices, which are often set to be unremovable. The most widespread and dangerous IEDs during the war were those with tensioned target sensors (tripwires).Due to the moral and physical obsolescence of reconnaissance and demining equipment in the units of the Armed Forces and the SES of Ukraine, manual reconnaissance and demining is the main method of reconnaissance and demining, which poses a great danger to sappers. To reduce the risk to the personnel of demining groups and pyrotechnic units, it is proposed to use a mechanical means of trawling for UXOs with tension target sensors. Based on the analysis of existing approaches to modeling demining processes, in particular the use of means for trawling tension sensors of explosive objects, a formalized description of the throwing of the element that trawls the tension sensors of the target is proposed, which, unlike the existing ones, takes into account the increase in the specific mass of the trawling means (a combination of the trawling element and the cable) during the flight. One of the most difficult issues in modeling is to determine the dependence of the flight parameters of the trawling element on the dynamics of the mass gain of the cable (cord). The kinematic parameters of the trawling element under study are: angle of departure, range, height, time, and flight speed. The proposed improvements to the mathematical model and the sequence of calculations will improve the accuracy of the results of modeling the process of trawling the tension sensors of an explosive target when substantiating the requirements for this type of demining equipment.
