THE EQUATION OF THE NON-STATIONARY THERMAL CONDUCTIVITY PROBLEM OF THE THERMOMETRICAL DEVICE CONSTRUCTIVE ELEMENT OF WEAPON SYSTEMS AND MILITARY EQUIPMENT

Abstract

Means of contact thermometry are widely used in various complexes of devices of weapons systems and military equipment. Such means basically involve the use of mechanical contact, in particular, bimetallic temperature transmitters, which are the most widely used thermometer variants in practice. To ensure the proper level of metrological and operational characteristics of bimetallic thermometers, reliable and adequate methods of calculating thermodynamic parameters (distributions of temperature, deformations, stresses caused by force and temperature loads) of the bimetallic package are necessary. The presented work describes an approach to the calculation of non-stationary temperature distribution in a solid-state element of a complex shape, which simulates the operation of a bimetallic thermometer sensor using the contact method. The calculated dependences obtained are the basis for modeling bimetallic thermometers of various structural forms and standard sizes. In order to constructively improve the thermometric system, it is proposed to make bimetallic plates non-one-pieces, but with additional structural inclusions, in the presence of which the temperature distribution and, accordingly, the stress state will approach to uniaxial one.
