Abstract：The articulated dump truck operates in harsh environments,and its transfer case must have high reliability and safety.Taking the articulated dump truck transfer case as the research object,a three-dimen-sional assembly model of the transfer case was established in SolidWorks software,the MSC.Patran software was used to establish a finite element model,and the Masta software was used to establish a load spectrum based on actual working conditions.The comprehensive displacement,comprehensive stiffness,gear contact stress,and other strength and stiffness characteristics of important components such as the transfer case housing,transmis-sion shaft,and transmission gear were analyzed.At the same time,the service life of the bearing under this load spectrum was calculated.The research provides reference and technical support for optimizing the structure,per-formance,and service life of the transfer case.
