The Modeling and Dynamic Simulation of a Spatial Variable-Link-Length Mechanism

The article is based on the motion characteristics of spatial link mechanism. According to a spatial practical given track, a spatial variable-length-link mechanism was designed. The model of the mechanism was constructed by MATLAB, and the complex motion track was planning to meet the need of precise planting, which supply theory basis for spatial mechanism applying to precision agriculture. By SolidWorks, the space motion simulation of the mechanism was also realized.
