Abstract: Rotary tiller gearbox bears alternate and complex dynamic load. To provide accurate load for its design, use UG software to establish 3D parametric modeling of main parts. Import 3D parametric modeling of blade and shaft into EDEM software. Use Bonding model to establish simulation model of soil particles. Through numerical simulation of the impact load from blade and soil, the dynamic load parameters of blade and shaft are derived. Obtain the model of gearbox housing in ANSYS software and import it into ADAMS software as flexible body. Based on the dynamic load parameters of blade and the model of gearbox housing, multi-body dynamical rigid-flexible coupling simulation analysis for rotary tiller is done with ADAMS software. ADAMS software solves the model by adopting Lagrange dynamics equation, rigidity integral algorithm and sparse matrix technology, through which the load model of gearbox is derived. Finally, import the load model into ANSYS software, and make stress and strain analysis on the rotary tiller gearbox, by applying the load same as recorded in load file, to find out design defects and weakness of rotary tiller gearbox, which provide references for the design of rotary tiller gearbox, and help to optimize the design.
