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

Abstract

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.
