Research of the operation of the turnstile support-fastening device during the transportation of a long-dimensional heavy load

The article analyzes the motion of a wheelset along path unequal length with shaft wear rails. authors have studied influence an external disturbing force on parametric system “wheel-rail”. considered problem is solved basis mathematical model interaction pair wheels and rail, taking into account additive effect stiffness rail vehicle. It shown that elasticity track in longitudinal direction allows to determine more precisely resonance regions evaluate decrease or increase acceleration level amplitudes impact unsprung mass
