Parametric Design and Simulation Analysis of Multi-linkage Transplanting Mechanism
摘要
Abstract
Aiming at present difficulties in design of multi-linkage mechanism, a multi-linkage parallel bar group transplanting mechanism of transplanter used in dry land was designed with parametric design method. A kinematic model of transplanting mechanism was established according to the structure. Based on ADAMS, a parametric model of the transplanting mechanism was established and a human machine interface for parametric design was developed. The human machine interface was used to set structural parameters for the transplanting mechanism and simulate static and dynamic trajectories of transplanter duckbill, the laws of displacement, velocity and acceleration of the duckbill transplanting tip were obtained. A set of appropriate parameters was optimized through adjustment of the parameters and analysis of the simulation results:Orientation Angle=42 °, L1=120 mm,L2=242 mm,L3=180 mm,L4=300 mm,L5=80 mm,L6=120 mm. Appropriate structural parameters of multi-linkage parallel bar group transplanting mechanism were obtained conveniently with the parametric design method.关键词
