Application of the Embedded Mechanical Systems for Ensuring the Preservation of Military Equipment Products Under Dynamic Impacts

Abstract

In the process of providing combat operations, the designs of military equipment products are subject to significant effects of both regular and non-regular dynamic loads, which can lead to their mechanical destruction. Among the dynamic loads acting on military hardware products, it is possible to identify short-term, caused by explosive and shock effects, and longterm vibrational loads that arise during transportation. As a result, there is the problem of ensuring the conservation of mechanical products of military equipment under dynamic impacts during the preparation and conduct of combat operations. The impact of a shock wave on military hardware products has a complex dynamic nature, depending on the wave parameters and the features of the object under consideration. Various results of this impact are possible, such as product destruction, turnover, change in the nature of motion, and others. The conservability of products with respect to the air shock wave is established experimentally. In addition to explosive loads, shock loads affect military equipment. In accordance with this, consider the local and general action of the thrust. Local action is characterized by the occurrence of local deformations and structural damage. The general action is accompanied by significant general deformations and destruction of the entire construction. The effect of prolonged vibration loads on military hardware products is mainly related to transportation processes. With prolonged cyclic loading, the destruction of the material of the structural elements can occur also at a stress amplitude less than the elastic limit. The article gives a definition of embedded mechanical systems and formulates their basic properties, which allow us to propose a hypothesis that in order to ensure the mechanical storage of products subject to dynamic influences, it is necessary to use embedded mechanical systems. Based on the nesting principle of mechanical systems, a method for increasing the retentivity of military equipment was proposed. The use of nested mechanical systems makes it possible to ensure the mechanical retention of military equipment by reducing the total energy supplied to the allowable value for the product to be stored.
