Based on such natural conditions as the terrain, landform, soil and climate as well as transplanting specifications and agronomic requirements, the 2ZY-l-type tobacco transplanting machine is designed. In this machine, the planter is associated with a crank-linkage mechanism. By using ADAMSrM to establish a model for planters, the parameters of this mechanism are obtained via parameterized modeling and optimization analysis. Therefore, this approach provides the ...
