Modeling of the springed part of a mobile vehicle

Abstract

During a full-scale invasion, the aggressor country changed the tactics of using mobile fire equipment. These changes led to the creation of highly mobile systems based on wheeled vehicles with an atypical firearm. As a wheeled vehicle, a "Pickup" type car is most often used, since its structural properties have room in the body for installing additional systems with subsequent masking of the selected vehicle. Such wheeled transport bases with an atypical firearm are already used in the Armed Forces of Ukraine both on the line of contact with the enemy and in civilian cities to protect the airspace, depending on the characteristics of the atypical firearm. Analysis of the creation and use of the mentioned systems revealed their certain shortcomings and the corresponding areas of improvement. The article considers the issue of the formation of an oscillating effect in the spring-loaded part of a wheeled vehicle when longitudinal disturbance from the use of a firearm is applied. The work is based on the analysis of requirements for longitudinal and transverse stabilization of the body of a wheeled vehicle. For this, an analysis of the characteristics of the existing types and schemes of the suspension of the "Pickup" type car was carried out. The obtained results are used to calculate the oscillating effect of a wheeled vehicle that occurs as a result of the use of an incendiary agent. The final goal of the work is to create a model of the rigidity of the "vehicle - firearm" system and to use this model to form a control effect of the automatic control system of the stabilization of the firearm. The presence of an automatic control system will increase the efficiency of the installed fire means.
