Abstract: In view of the problems of overgrown weeds and garbage in the embankment grass at this stage, a dike grass care machine is designed in this article. Since the operating environment of the device is mainly the embankment slope, the operation condition of the device on the slope is simulated, and the simulation software ADAMS is used to simulate the virtual prototype of the whole vehicle. The trolley model is simplified and adjusted through the software so as to realize the simulation operation of the trolley climbing the embankment grass at different angles. The simulation results show that the embankment grass care machine can achieve stable climbing on the ramp at different angles; at the same time, the rollover can be effectively avoided through the center of gravity transfer module.
