Determination of dynamic loading of bearing structures of freight wagons with actual dimensions

The determination of the dynamic loading bearing structures main types freight wagons with actual dimensions under operating conditions is carried out. inertial coefficients are determined by constructing their spatial models in SolidWorks software package. Two cases – vertical and longitudinal planes have been taken into account. studies were out a flat coordinate system. When modeling wagons, it was account that they move empty state butt unevenness elastic-viscous track. supported bogies 18-100. solution differential equations motion Runge-Kutta method MathCad determining calculation made for case shunting collision or "jerk" (tank wagon). accelerations acting on determined. research results will help to determine possibility extending operation exhausted standard service life. It has established indicators dynamics load-carrying structural elements within permissible limits. So, gondola wagon, acceleration structure 4.87 m/s2, covered wagon 5.5 5.8 tank 4.25 hopper 4.5 m/s2. 38.25 38.6 38.9 27.4 38.5 This makes possible develop conceptual framework restoring effective functioning outdated wagons. conducted be useful developments clarifying existing methods life resource
