目的:减少玫瑰香橙在包装、运输过程中的损伤.方法:根据玫瑰香橙的基础几何数据及TPA试验、穿刺试验得出的最大压缩力、穿刺力,构建有限元模型对玫瑰香橙进行压缩仿真模拟.结果:玫瑰香橙直径范围为58.2~78.6 mm,平均质量为169.746 g,赤道部果皮平均厚度为3.1 mm,最大穿刺力为6.26 N,平均破裂力为126.802 N.结论:玫瑰香橙赤道部位的抗压能力相对较弱,应避免受到挤压、冲击;玫瑰香橙在采摘、运输过程中能承受的力不宜超过100 N.
Objective:Reduced the damage of rose orange in the process of packaging and transportation,and provided a theoretical basis for postharvest storage and spectral quality testing.Methods:According to the basic geometric data of rose orange and the maximum compression force and puncture force obtained from TPA test and puncture test,the finite element model was constructed to simulate the compression of rose orange.Results:The diameter of rose orange ranged from 58.2 mm to 78.6 mm,the average weight was 169.746 g,the average thickness of peel at the equator was 3.1 mm.the maximum puncture force was 6.26 N,and the average rupture force was 126.802 N.Conclusion:The pressure resistance of rose orange equator is relatively weak to avoid extrusion and impact,and the force that rose orange can bear in the process of picking and transportation should not exceed 100 N.
