摘要： Transplanting represents a vital technique in contemporary vegetable cultivation; mechanized transplanting entails a complex process characterized by interactions among machine, soil, and plants, which ultimately constrains the quality of mechanized transplanting. Currently, due to the unclear mechanism of machinesoil-plant interaction, it is difficult to solve the problem of transplanting verticality. To this end, this study established a machine-soil-pot seedling coupled simulation model through EDEM-Recurdyn co-simulation to analyze the disturbance of the soil and pot seedling by the transplanter during the transplanting process. Simulation experiment results indicate that the trajectory eigenvalue of the transplanting point and the opening angle of the duckbill are the main factors affecting transplanting effects. Through regression modelling, it is predicted that when the eigenvalue lambda is 1.1, the duckbill opening angle gamma is 33.3 degrees, and the opening time t is 0.4 s, the transplanting effects are optimal, corresponding to the soil backflow ratio of 0.44, the soil disturbance ratio of 1.29, and the verticality of 79.83 degrees. By comparing the results of the simulation with field experiments, the average errors of soil backflow ratio, soil disturbance ratio, and verticality were 2.14 %, 2.46 %, and 1.86 %, respectively. The experiment results show that the simulation model can effectively reflect the physical changes during the transplanting process and can provide a reference for the optimization of the transplanting device design.
