Abstract

Abstract: In order to solve the problems of low mechanization of agriculture in hilly terrain and the inability of large agricultural machinery to adapt to hilly terrain operations, a multifunctional micro-electric autonomous driving operation platform had been designed.According to the design concept of dual front end and no cab, the transmission mechanism was driven by dual motors, the driving mechanism was driven by triangular track wheels, and the steering mechanism adopted a four-wheel co-directional steering mechanism and differential steering control system, so that the work platform could drive diagonally to meet the requirements of narrow hilly terrain operations. A 1∶5 prototype model was established to conduct experimental analysis on the ability of the work platform to cross trenches and vertical obstacles. The results showed that the prototype model had a strong ability to cope with complex terrain, with a maximum width of 4 cm for crossing trenches, a height of 5 cm for crossing vertical obstacles, and a minimum turning radius of 20 cm. It could basically adapt to scenarios such as trenches and ramps. From this, it could be seen that the technical solution of the work platform designed in this study was feasible and could meet the actual needs of orchard users in hilly terrain. At the same time, the product development process using theoretical calculations, simulation analysis, and model validation provided new ideas for saving the research and development costs of new agricultural machinery products.
