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。
The orientation mechanism of apricots motion in directional conveying was studied.Euler dynamic equations for apricots motion were established satisfying actual engineering conditions to provide necessary design rules for optimal design of apricots orientation and segmentation devices.Lyapunov stability principle was used to judge the stability of apricots’dynamic equations.The apricots orientation motion was simulated numerically with their dynaimc equations and MATLAB software.The simulation and test results showed that apricots roll around their maximum inertial axis （horizontal diameter）,their motion tends to be stable and the orientation effect is good,after their entering randomly a delivery system;the simulation results agree well with the test ones,so the correctness of the orientation theory of apricots motion is verified.
