针对实际电磁振动定向装置进行多因数多水平试验研究时存在周期长、受加工精度影响大等问题,利用ADAMS等软件建立参数化的玉米种子电磁振动定向装置和种子仿真模型,通过试验测定玉米种子与定向滑槽之间的接触参数,系统定义玉米种子与定向滑槽之间的接触。从振动分析、接触力和模型振动效果3方面对该模型进行验证。结果表明:该电磁振动定向装置和玉米种子的仿真模型振动效果符合实际,接触的定义准确,激振力与振幅线性相关,符合实际弹簧片变形规律和电磁振动理论,可以用来代替实际电磁振动装置进行电磁振动下玉米种子姿态翻转与定向传输的模拟仿真试验和优化试验。
Aiming at the problems of long period and large influence of machining accuracy, the multi-factor and multi-level experimental study of the actual electromagnetic vibration oriented device has made use of ADAMS and other softwares to establish the parameterized corn seed electromagnetic vibration directional device and seed simulation model. The corn seed And the orientation of the chute between the contact parameters, the system defines the contact between the corn seed and the orientation chute. The model is validated from vibration analysis, contact force and model vibration effect. The results show that the vibration effect of the electromagnetic vibrating directional device and the corn seed simulation model is in line with the actual situation, the definition of contact is accurate, and the exciting force is linearly related to the amplitude, which accords with the actual deformation law of spring leaf and electromagnetic vibration theory.
