中文摘要：

研究杏果在实际输送过程中定向机理的问题，构造满足实际工程条件的欧拉动力学方程，可为杏果定向装置的制造优化提供可行性依据。为此，针对杏果在定向装置内的输送情况，建立杏果的力学分析模型，运用ADAMS动力学分析软件对刚柔耦合的输送系统进行运动仿真，对杏果的定向过程进行试验模拟验证。运动仿真结果表明，杏子随机进入输送系统后逐渐实现绕杏果横径方向作纯滚动。杏果在输送过程中的运动状态可由运动微分方程全面描述，运动仿真模拟和实验数据相符，有效地验证杏果定向理论的正确性。

英文摘要：

The research studied the apricots orientation mechanism during actual conveying , constructed Euler dynamic equations meeting actual project conditions , and provided theoretical basis for the development and manufacture of orien-tation device We 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 ADAMS dynamics analysis soft-ware , and made the experimental verification of apricots orientation process based on high -speed camera The results of motion simulation showed that apricots made gradually pure rolling around horizontal diameter after entering delivery sys -tem random 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 .
