摘要研究杏果在实际定向输送过程中的定向机理，构造满足实际工程条件的欧拉动力学方程，为杏果定向、切分装置的设计优化提供必要的设计依据。应用李雅普诺夫稳定性原理对杏果动力学方程进行稳定性判定，借助于Matlab数学分析软件对杏果物理模型进行数值模拟仿真，运动仿真及试验结果表明杏果随机进入输送系统后逐渐实现绕杏果最大主惯性轴（横径）方向作滚动，并趋于稳定，定向效果良好。运动仿真模拟和试验数据相符，验证了杏果定向理论的正确。

Abstract：Established the apricots mechanics analysis model about apricots transporting situation in the directional device, made the motion simulation of rigid-flexible coupling delivery system by use of Matlab mathematical analysis software, and made the experimental verification The dynamic stability of apricots orientation process based simulation experiments to confirm the findings. The results of motion simulation showed that apricots made gradually pure rolling around horizontal diameter after entering delivery system random, And tend to be stable, orientation well.The state of apricots motion during conveying was described completely by differential equations of motion. The simulated results agree to the experiment,and verify the correctness of the theory of apricots orientation.

Key words： Apricots transportation Orientation Euler dynamic equations Motion simulation；stabilization
