Weight Reduction of Bottom Centre Bearing Plate of freight rolling stock

  Dr. Sanjay Shukla,  Manish Pandey

Indian railway is designing higher axle load freight rolling stock for high speed freight dedicated tracks to improve through put. Weight and speed are always crucial parameters for high speed vehicles. Bottom Centre Bearing Plate is made of cast steel and connected between car body and bogie to transfer the loads from car body to track in static condition further it bears longitudinal traction, braking forces and centrifugal forces arising on curved track in dynamic environment. Weight of bottom centre bearing plate of freight rolling stock bogie frame has been reduced in present research work by performing parametric study of structural analysis in MSC FEA interface. Indian Railway loading and boundary conditions has been applied on finite element model of initial modified design of the bottom bearing plate. The weight of the modified centre plate has been approximately reduced by 2.72% than initial one. Natural frequencies and corresponding mode shapes of initial and modified design are compared to verify the topology of the component. The time dependent tenser values at critical zones of initial and modified design of the bearing plate have been verified on Goodman diagram.
