Abstract
This paper concerns mainly on the accelerated life test for railway vehicle bogie frame including test bench design and test loading spectrum design. Test bench is a dynamic system including hydraulic elements, kinematic joints, force elements and control elements. A hybrid rigid-flexible dynamic simulation model is introduced to design the loading mechanism and actuators layout. Vehicle system dynamics simulation is introduced to obtain loads histories for different operation events. The simulation data is extrapolated for test spectrum using multiaxial rainflow projection method.
