    摘要:

    针对蝇蛆养殖行业中,蛆料分离技术的落后、机械化程度低、自动化程度低等缺陷,提出了一种蝇蛆分离用1T2R并联式振动筛,能够实现沿z轴的平移、绕x轴的转动和绕y轴的转动,可以高效地实现蛆料的分离。首先对该机构进行运动学建模,并且给出了运动学的正解和反解,将建立的运动学数学模型导入Matlab中,得到理论运动曲线;并且在Pro/E中建立该振动筛的虚拟样机模型,利用Mech/Pro给虚拟样机添加运动副并导入到ADAMS软件中,添加驱动后得到仿真运动曲线。结果显示仿真曲线与理论曲线完全一致,从而验证运动学数学模型的正确性。

    Abstract:

    In order to solve the problems of backward separation technology between maggots and substrate, low level of mechanization and low level of automationin the industry of maggots breeding,a 1T2R multidimensionalparallelmaggots sieving machine was present.Translation along the zaxis, rotation around the xaxis and yaxiscouldbe achieved,so efficient separation was realized between maggots and substrate.On the one hand, kinematic model was established for the mechanism, then positive and inverse equation of kinematics was calculated, which was led to Matlab to acquire theoretical motion curve.On the other hand, three dimensional (3D)model of sieving machine was established by Pro/E, andit was led into ADAMS by interface software Mech/Pro to acquire simulative motion curve after adding drivers.The results show that the simulative curve is completely in consistent with the theoretical curve, so the correctness of the kinematic mathematic model was verified.
