Using 3D modeling software

geometric model of the wheel planetary gear reducer structure is established

based on heavy-duty truck wheel reducer planetary gear structure and the loading characteristics

a planetary gear structure of three-dimensional finite element model is established.By explicit dynamics software

dynamics simulation of the planetary gear structure is carried out

and in motion

structure loading force the maximum stress of the position and trend of the stress is analyzed

conclusions can provide the basis for the design and analysis of gear structure.
