On the basis of the analysis of the kinematics of the new differential designed by this paper, and using the optimization algorithm provided by the simulation software ADAMS itself, the constrained conditions of the design variables and their parallel design are determined by taking the differential volume as the objective function to minimize the volume. Its optimal exercise design. (1) The kinematic characteristics of the new agricultural machinery differential for complex conditions are obtained. (2) Through the comparative analysis, the simulation results are consistent with the theoretical design, which verifies the correctness of the structural design of the new agricultural differential.
