摘要/Abstract

摘要： 为提升链—板式银杏果脱壳机作业性能，采用Box-Benhnken中心组合设计理论，以脱壳机脱净率及破损率为响应值，以链板速度、一级间隙、二级间隙为影响因素，设计三因素三水平二次回归正交试验，建立响应面数学模型，开展方差分析，研究各因素对设备作业质量的影响规律，并优化参数组合。试验结果表明，各因素对脱净率影响重要性次序：二级间隙、一级间隙、链板速度；对破损率重要性影响次序：链板速度、二级间隙、一级间隙；最优参数组合：链板速度为0.4m/s，一级间隙为11.9mm，二级间隙为10.5mm。验证试验表明，优化后的作业设备脱净率为85.93%，破损率为4.84%，试验值与模型预测值间的相对误差均小于5%，达到预期效果。该研究可为后续银杏果脱壳相关设备研究提供参考。

Abstract: In order to improve the operational performance of chain-plate ginkgo nut huller, Box-Benhnken central combination design theory was adopted. The hulling rate and damage rate of the huller were selected as the response values, and the chain plate speed, primary clearance, and secondary clearance were selected as the influencing factors, a three-factor and three-level quadratic regression orthogonal test was designed, a response surface mathematical model was established and variance analysis was conducted. The impact of each factor on the operating quality of the huller was studied, and the parameter combinations were optimized. The test results showed that the order of importance of each factor on the hulling rate was secondary clearance, primary clearance, chain plate speed, and the order of importance on the damage rate was chain plate speed, secondary clearance, primary clearance, and the optimal parameter combinations was chain plate speed of 0.4m/s, primary clearance of 11.9mm, and secondary clearance of 10.5mm. The validation test showed that optimized operation of the equipment hulling rate was 85.93%, the damage rate was 4.84%, and the relative errors between the experimental values and the model predicted values were less than 5%, which achieved the expected results. This study can provide a reference for the subsequent research of ginkgo nut hulling related equipment.
