Abstract (English): In this paper, the mechanical injury evaluation standard of Cerasus humilis was established based on extrusion deformation energy and fruit storage days. The key factors affecting extrusion deformation were determined by analysing the contact force during combing. The single-factor test and three-factor, three-level quadratic regression orthogonal test were carried out by using the fruit removal rate and damage rate as the evaluation indices and the comb distance, combing speed and comb rod radius as the influencing factors. Results showed that the fruit removal rate decreased and the damage rate initially decreased and then increased with the increase in comb distance; with the increase in combing speed, the fruit removal rate remained unchanged and the damage rate increased; with the increase in comb rod radius, the fruit removal rate initially increased and then decreased, while the damage rate initially decreased and then increased. The order of influence on the fruit removal rate was comb rod radius > comb distance > combing speed. The order of influence on the damage rate was combing speed > comb distance > comb rod radius. Response surface methodology obtained the following optimal parameters: comb distance of 9 mm, combing speed of 340 mm/s and comb rod radius of 8 mm. A validation test was carried out on a combing test bench under the optimised parameters. The fruit removal rate was 96.89% and the damage rate was 6.36%. These values were consistent with the results of optimum parameters; thus, the regression model was reliable. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 本文基于挤压变形能和果实存放天数,建立钙果机械损伤评价标准,分析钙果在梳脱过程中的接触受力, 确定影响挤压变形的关键因素。以脱净率和损伤率为评价指标,以梳齿间距、梳脱速度和梳齿杆半径为影响因 素分别进行单因素试验和三因素三水平二次回归正交试验,结果表明:当梳齿间距增大时,脱净率降低,损伤 率先减小后增加;梳脱速度增加时,脱净率基本保持不变,损伤率逐渐增大;梳齿曲率半径增加时,脱净率先 增加后减小,损伤率先减小后增加。对脱净率的影响显著顺序为:曲率半径>梳齿间距>梳脱速度;对损伤率的 影响显著顺序为:梳脱速度>梳齿间距>曲率半径。基于响应面法进行参数优化,得到最佳组合参数:梳齿间距 为9 mm,梳脱速度为340 mm/s,曲率半径为8 mm。以优化后的参数组合,在梳脱试验台上进行验证试验, 其结果为:脱净率96.89 %,损伤率6.36 %,与优化参数结果基本吻合,回归模型可靠。 [ABSTRACT FROM AUTHOR]
