首先对工业大麻收割机铺放角形成机理进行研究，然后采用二次正交旋转组合试验方法设计试验并用Design-Expert进行数据处理，建立铺放角的回归数学模型，通过响应曲面方法分析各因素交互作用对铺放角的影响，并根据实际生产设计要求对回归模型进行多目标优化，得出工业大麻收割机铺放角的最优组合为：前进速度为0.7 m/s，速比为1.40，割茬高度为95 mm，此时铺放角最小，其值为124.9°。
将优化参数在仿真和田间验证试验，仿真验证试验结果表明，在最佳参数组合条件下，铺放角仿真值为125.2°，与理论值相对误差为0.24%。
田间试验结果表明，在最佳参数组合条件下，工业大麻植株平均铺放角为121.8°，与理论值相对误差为2.5%。
该研究结果可为工业大麻收割机结构改进和作业参数控制提供参考。

Moreover, the operating parameters were tested and optimized based on the central composite design theory, and carried out multi-objective optimization with the minimum laying angle as the response index. Firstly, the formation mechanism of the laying angle of hemp harvester was studied. Secondly, a test was designed with the quadratic orthogonal rotational combination test method, with the data being processed by Design-Expert. A regression mathematical model of the laying angle was built, and the influence of the interactions between factors on the laying angle was analyzed with the response surface method. Furthermore, multi-objective optimization was conducted on the regression model according to the actual production design requirements. As a result, the best combination was obtained, that is, when the forward speed is 0.7 m/s, speed ratio 1.40, and stubble height 95 mm, the minimum laying angle can be obtained, namely 124.9°. The optimization parameters were verified by the simulation and field tests. The simulation test showed that the simulated laying angle is 125.2°, with a relative error of 0.24% from the theoretical value, under the best combination of parameters. The field test showed that the average laying angle of hemp plant is 121.8°, with a relative error of 2.5% from the theoretical value, under the best combination of parameters. The results may provide a reference for the structural improvement and operating parameter control of hemp harvesters.Keywords: agricultural machinery, hemp, laying angle, rigid-flexible coupling model, optimization, response surface analysisDOI: 10.25165/j.ijabe.20231604.7978Citation: Huang J C, Tan L, Tian K P, Zhang B, Ji A M, Liu H L, Shen C.
