Abstract：Withthebogieframeofahybridrail vehicle being theresearchobject，thispaperuses HyperMeshfiniteelement software tocalculatethestaticstrengthoftheframeunderextraordinaryloadconditionandsimulatedoperationloadconditionin accordancewiththerelevantspecifications.Basedonthestrength calculationresults，topologyoptimizationiscariedoutforthe internalribsof thesideandendbeamsoftheframe，andtheribschemeisdeterminedconsidering theactualprocesing conditionsandotherfactors.Thesizeoftheoveralltheframeisoptimized.Bothstaticandfatiguestrengthsoftheoptimizedframe meet the regulatory requirements，and the mass of the optimized frame is reduced by 6.83% ，with significant lightweight effect， which provide favorablereference for the structural design of the bogie frameof hybridrail vehicle in the future.
