| 为了解决核桃预处理及破壳中的姿态定向问题，首先，根据核桃的物理特性和外形特征，设计特定振动定向台，并确定其空间位置和结构尺寸参数，然后对核桃在振动定向台上的运移姿态变化过程进行理论分析，探究核桃在振动运移中的姿态定向原理；其次，搭建试验台架，以纵向定向成功率和定向所需时间为指标进行单因素试验，选取电压、振动频率、振动台倾角的最佳取值范围；最后，根据单因素试验结果开展Box-Behnken试验，对参数进行优化。结果表明：基于电磁振动设计了一台核桃姿态定向装置，并确定对该装置影响最大且试验中最易控制的3个因素为电压、振动频率和振动台倾角。当电压为118 V、振动频率为81.6 Hz、振动台倾角为3°时，核桃的纵向定向成功率为89.98%，尖端定向成功率为74.36%。该装置定向成功率较高，可用于核桃预处理和破壳中的姿态定向。 |

| In order to solve the problem of attitude orientation in walnut pre-processing and shell breaking, firstly, according to the physical properties and shape characteristics of walnuts, a specific vibration orientation platform was designed, and the spatial position and structural size parameters were determined, and then the theoretical analysis of walnuts on the vibration orientation platform was carried out to investigate the attitude orientation principle of walnuts in vibration transport. Secondly, the test rig was set up, and the longitudinal orientation success rate and time required for orientation were taken as the indexes, and the voltage, vibration frequency and inclination angle of the vibration platform were selected to conduct a single-factor test to find the range of values of each factor. Finally, Box-Behnken test was carried out to optimize the parameter according to the results of single-factor test. The results showed that a walnut attitude orientation device based on electromagnetic vibration was designed, and voltage, vibration frequency and inclination angle of the vibration platform had the greatest impact on the device and they were the easiest to control during the test. Under the conditions of voltage 118 V, vibration frequency 81.6 Hz, and inclination angle of vibration platform 3°, the longitudinal orientation success rate was 89.98%, and the tip orientation success rate was 74.36%. The device has a high success rate in orientation and can be used for attitude orientation in walnut pre-processing and shell breaking. |
