The Research of the Stability of Rotation Super-Rice Seed Based on Single Axisymmetric Characteristics

Abstract:

Preliminary tests found that super-rice seeds could be oriented by rolling them down with a guided plate. The rotation of the seed around the shortest axis was found to be unstable, while rotation around another two axes was found to be stable. The purpose of the current study was to examine whether this orientation phenomenon could be explained in terms of inertial characteristics of seeds. According to the surface feature of the seeds, an ellipsoid geometrical model was made. Euler dynamical model were built to analysis the movement stability of the seeds. The effect of parameters on movement stability was analyzed by the method of numerical simulation.
