Abstract: Aiming at the problems existing in the analysis and optimization design of the working process of planter, we proposed a coupling method of multiple rigid body dynamics (MBD) and discrete element method (DEM). By  integrating the selfdeveloped  multirigid dynamics simulation software with discrete element analysis software, we developed a new type of CAE software—AgriCAE (agricultural computer aid engineering), introduced the implementation method of the software, and verified the feasibility and effectiveness of AgriCAE software by an example.

Key words: CAE software, computer simulation, optimization design, multiple rigid body dynamics (MBD), discrete element method (DEM), planter
