The general explicit nonlinear finite element program ANSYS/LS-DYNA was used as a tool to research the influence of tillage depth and operating speed on operating resistance of the multiplex-modality subsoiler, as well as to study the significance of operating resistance reduction of the multiplex-modality subsoiler compared with the standard arc-shape subsoiler. In order to prove the reliability of the finite element analysis method, the operating resistance of the multiplex-modality subsoiler and the standard arc-shape subsoiler was tested in a soil bin. The result showed that there was a same varying trend between the operating resistance data obtained by the finite element method and soil bin test, and the finite element method was suitable to the research of the performance of subsoiling. With the fixing operating speed of 4~5km/h, average operating resistance of the multiplex-modality subsoiler reduced by 44.07%, 43.71% and 33.83% than of the standard arc-shape subsoiler, based on tillage depth of 300mm, 350mm and 400mm, respectively. All these data proved that the multiplex-modality subsoiler had a significant effect on operating resistance reduction.
