The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。
