| 针对使用实际直线电磁振动定向装置进行优化试验时效果不理想的问题，利用ADAMS建立玉米种子直线电磁振动定向装置参数化仿真模型，从传输稳定性角度确定3个影响因素（振幅A、台阶高度H和倾角J）的试验范围，以传输速度v和定向成功率ρ为指标，进行直线电磁振动下玉米种子定向传输的模拟仿真试验，得到了直线电磁振动定向装置的最佳工作条件：A=0.6 mm、H=3 mm、J=4°。通过实际直线电磁振动定向装置对该最佳工作条件进行验证，结果表明：玉米种子的平均传输速度和定向成功率与仿真结果基本一致，并且能够保证传输稳定性，说明该最佳工作条件正确合理。 |

| Abstract: |
| Aiming at the problem that the effect of the optimization experiment was not ideal using the actual linear electromagnetic vibration directional device for corn seeds,a parameterized simulation model of linear electromagnetic vibration directional device by ADAMS was built firstly,and a simulation test of corn seeds' directional transmission under linear electromagnetic vibration was the carried out.Three factors,e.g.vibration amplitude A,step height H and inclination angle J were obtained from the perspective of transmission stability.The average transmission speed (v0) and directional success rate (ρ) were also taken as index.Then the optimal working conditions of the linear electromagnetic vibration orientation device were obtained,which isA 0.6 mm,H 3 mm and J 4°.A directional transmission test was carried out on corn seeds by actual directional device based on electromagnetic vibration to verify the optimal working conditions.The results showed that the transmission speed and the directional success rate of corn seeds were basically consistent with the simulation results,and the transmission stability could be guaranteed.In conclusion,the optimal working conditions were proved to be correct and reasonable. |
