METHOD OF APPROXIMATE DETERMINATION OF AVERAGE TEMPERATURE OF STRUCTURAL MEMBER OF BRAKING UNIT AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2002 - IPC

FIELD: measurement technology; measurement of average temperature structural member of braking unit. SUBSTANCE: on base of deformation of structural member at the beginning of operation of braking unit initial temperature of structural member T₀ and its initial modulus of elasticity E₀. are determined. At the moment t₁...t_n after beginning of operation of brake, brake pressure P₁...P_n and deformation h₁...h_n. of structural member are determined. On basis of data thus obtained, approximate elastic component of deformation h_(l...n)el and approximate thermal component of deformation h_(l...n)th are determined. According to dependence of deformation versus temperature, approximate of structural member of braking unit T₁...T_n at respective moments of time t₁...t_n is determined. Device used for determination of average temperature of structural member of braking unit includes wear-compensating unit, two measuring sensors: deformation sensor and pressure sensor which are connected to computing unit and timer. Computing unit is made in form of microprocessor; its memory retains E=f(T) characteristics. Deformation sensor is made in form of cam turn angle sensor of braking drum. EFFECT: simplification of method; enhanced economical efficiency. 9 cl, 1 dwg
