Oscillation simulation of fixed wheel equipment while railway transportation
The article states the results of building a dynamic model of wheel equipment, set on the platform as a one-mass mechanical system "platform - springing element - wheel equipment body". Presenting the character of a driving force change as a harmonic law, an equation of vertical oscillations of wheel equipment with subject to elastic and dissipative system characteristics (flexible fastening elements from annealed wire and tyres) was deduced. The got mathematical models of vertical oscillations of wheel equipment on a car allow to define the vertical displacement of wheel equipment relative to the car, by the quantity of which the elastic forces in fastening elements with the consequent estimation of their loading can be found by the criterion of these forces' allowed value or by the criterion of wheel equipment valid dislocation.
