Abstract

Sposób równoczesnego pomiaru sił, (Y) poziomej działającej prostopadle do płaszczyzny symetrii szyny kolejowej i (Q) działającej na szynę kolejową oraz wyznaczania stosunku tych sił oznaczanego (Y/Q), charakteryzuje się tym, że zespołem przetwornika (1) do pomiaru sił poprzecznych oddziaływania koła zestawu kolejowego na szynę mierzy się siłę (Y) poziomą, działającą prostopadle do płaszczyzny symetrii szyny kolejowej i równocześnie dwoma zespołami przetworników (6) do pomiaru sił tnących mierzy się siłę (Q), stanowiącą składową pionową sił działających na główkę szyny kolejowej, przy czym sygnały z przetworników tensometrycznych zamontowanych w zespole przetwornika (1) do pomiaru sił poprzecznych doprowadza się do pierwszego układu elektronicznego (U(Y)), w którym uzyskuje się sygnał (S(Y)), zaś sygnały z przetworników tensometrycznych, zamontowanych w zespołach przetworników (6) do pomiaru sił tnących, doprowadza się do układu pomiarowego (U(Q)), w którym uzyskuje się sygnał (S(Q)), sygnały (S(Y) i S(Q)), doprowadza się do trzeciego układu elektronicznego (U(Y/Q)), w którym wyznacza się stosunek sił (Y) do (Q), a uzyskany sygnał (S(Y/Q)) przetwarza na sygnał wyjściowy.The method of simultaneous measurement of forces (Y) horizontal acting perpendicular to the plane of symmetry of a rail and (Q) acting on the rail and determination of the ratio of these forces marked (Y / Q) is characterized by the fact that the transducer assembly (1) for measuring transverse forces the impact of the wheel set wheel on the rail is measured horizontal force (Y) perpendicular to the plane of the rail symmetry and simultaneously two sets of transducers (6) for measuring shear forces measure the force (Q), which is the vertical component of the forces acting on the rail head, where signals from strain gauges mounted in the transducer assembly (1) for measuring transverse forces are fed to the first electronic system (U (Y)), in which the signal (S (Y)) is obtained, and signals from strain gauges mounted in transducer assemblies (6) for measuring shear forces, led to uk measuring device (U (Q)), in which the signal (S (Q)), signals (S (Y) and S (Q)) are obtained, are fed to the third electronic system (U (Y / Q)), in which determines the ratio of forces (Y) to (Q), and converts the obtained signal (S (Y / Q)) into an output signal.
