【摘要】 以油菜为作业对象,建立了单风机单层振动筛清选装置的虚拟样机模型,并在不同工作参数下,对油菜在清选装置中的运动规律进行了仿真实验,得出了对油菜清选影响较大的工作参数,仿真实验结果与室内台架试验结果一致,表明了虚拟样机的可靠性。更多还原

【Abstract】 Aimed at the screening process of single rape material, use ADAMS, one of the virtual prototype software, to construct the virtual three-dimensional entity model of the cleaning unit of single exhaust cleaning fan combining single banked oscillating sieve. Carry on a simulation and virtual test on it. Finally analyze the result of virtual test and find out some parameters which influence cleaning course most. The results indicate that the cleaning losses will increase as the crank is longer than 35mm or the crank speed is lower than 270 rpm. And lower rotational speed of centrifugal fan is helpful to reduce the cleaning losses.更多还原
