Strength Assessment of Elastic Fuel Reservoirs During Accelerated Refueling of Combat Vehicles

Abstract

The possibility of increasing the survivability of the system of refueling combat vehicles during combat operations through the development of a new method that reduces refueling time and the use of new technical means to implement it is substantiated. The essence of the method of accelerated refueling of combat vehicles is to place an elastic fuel reservoir (EFR)under the combat vehicle wheel and run it over at low motion velocity, resulting in the fuel displacement from EFR to the fuel tank of the vehicle being refueled. The study results indicate the feasibility of accelerated refueling of combat vehicles by this method. A mathematical model for determining the pressure in the EFR run over a vehicle wheel was refined in this study. A mathematical model for determining the stress-strain state of an EFR loaded with internal excessive alternating pressure was proposed, allowing one to assess stresses arising in the EFR wall when refueling combat vehicles and optimize the EFR design. Experimental results on the of accelerated refueling of vehicles confirmed the efficiency of the proposed refueling method and the EFR design.
