摘要

蜜桃损伤的可视化和分析对于减少采后处理过程中冲击损伤的发生非常重要。本文采用有限元模拟方法对蜜桃的撞击损伤进行可视化分析。首先,通过碰撞装置获得蜜桃与合金钢、高密度聚乙烯(HDPE)和可膨胀聚乙烯(EPE)表面碰撞时的最大力、损伤面积、损伤体积和吸收能量等力学参数。然后,通过对蜜桃果肉的压缩试验获得了弹性模量和泊松比。最后,用有限元法模拟了蜜桃与不同材料表面的碰撞过程。结果表明,参数测量值与模拟值之间的最大误差小于 25.1%。该研究为蜜桃包装材料的选择和各种农产品的生物力学特性提供了参考。 实际应用 冲击损伤是蜜桃采后处理过程中最常见的机械损伤之一,定量研究蜜桃的冲击损伤对减少蜜桃在包装和运输过程中冲击损伤的发生具有重要意义。该研究表明,使用有限元法对蜜桃的冲击损伤进行定量预测和评估是可行的。此外,选择合适的包装材料还可有效减少蜜桃在运输过程中冲击损伤的发生。研究结果不仅能为蜜桃的包装和运输等环节提供理论支持,还能为各种农产品的生物力学特性提供参考。

Study on impact damage visualization of honey peach based on finite element

Visualization and analysis of damage in honey peaches is important to reduce the occurrence of impact damage during postharvest handling. The finite element simulation method was used to visualize impact damage of honey peach. Firstly, the mechanical parameters such as maximum force, damage area, damage volume and absorbed energy during the collision between honey peaches and the surfaces of alloy steel, high density polyethylene (HDPE) and expandable polyethylene (EPE) were obtained by the collision device. Then, the elastic modulus and Poisson's ratio were obtained by compression tests of honey peach pulp. Finally, the process of collision between honey peaches and different material surfaces were simulated by finite element method. The results showed that the maximum error between the measured and simulated values of parameters were less than 25.1%. The study provides a reference for the selection of packaging materials for honey peaches and the biomechanical properties of various agricultural products.

Practical applications

Impact damage is one of the most common mechanical injuries in postharvest handling of honey peaches, and it is of great significance to quantitatively study the impact damage of honey peaches to reduce the occurrence of impact damage of honey peaches during packaging and transportation. The study shows the feasibility of using the finite element method for quantitative prediction and assessment of impact damage in honey peaches. In addition, the selection of suitable packaging materials can be used to effectively reduce the occurrence of impact damage of honey peaches in the transportation process. The results of the study can not only provide theoretical support for the packaging and transportation of honey peaches and other aspects, but also provide a reference for the biomechanical properties of various agricultural products.
