摘要
对割前脱联合收割机摘脱割台流场特性进行了分析, 认为摘脱滚筒周围气流速度随极半径增加而减小,方向与极半径垂直,建立了气流流速分布方程。在此基础上, 构造了摘脱割台脱出物运动方程数学模型,
The air flow rate around stripped rotor was analyzed and studied.The velocity decreased with the increasing of the radius and the direction was perpendicular with the direction of radius.The air velocity distribution equation was built,on which the detached grain kinematics equation math model was constructed,and the simulation in computer conducted.
