In the process of mechanized production of mulberry, falling collision damage is one of the main damage forms, which causes serious damage and accelerates fruit decay.Through the drop collision test and simulation analysis of mulberry fruit, the relationship between drop conditions and fruit damage degree was established, so as to provide reference for reducing fruit falling damage. The drop test is carried out. The relationship between factors and indicators is established. The drop height, fruit plate angle, fruit plate material, and drop direction were taken as factors, and then the energy loss was selected as indicator. The drop process of mulberry fruit is analyzed by numerical simulation, and the maximum stress and deformation of mulberry fruit are analyzed. With the increase of the drop height, the kinetic energy of the fruit increases. When the fruit plate material is pearl cotton, the drop height changes from 200 to 1000 mm, the energy loss of fruit falling increases from 4.42 Â 10 À0.3 J to 2.14 Â 10 À0.2 J. When the drop height of fruit is 200 mm, the angle of fruit plate is 30 , and the material of fruit plate is pearl cotton, the minimum energy loss of fruit is 3.39 Â 10 À0.3 J, the fruit damage was the least. This study can provide a reference to reduce the damage of mulberry fruit in the process of mechanical harvest and transportation. Practical ApplicationsThe existing mulberry harvesting methods are manual harvesting, while the vibration harvesting methods have high harvesting efficiency and serious damage. When the harvesting parts hit the tree trunk, the mulberry fruit will leave the tree and falls onto the fruit-receiving device in the process of mechanical harvesting. There will be a collision and falling of the mulberry, which may cause serious damage. Therefore, in the process of mulberry fruit harvest, transportation, the falling, and collision damage is the main damage form.At present, there is few research on the drop impact damage test of mulberry fruit. In this study, the effects of mulberry falling direction, fruit plate material and drop height on mulberry damage were discussed by drop experiment. Then, the optimization results were carried out. The change and distribution of stress and strain in the process of collision were analyzed by numerical simulation, and the relationship between falling conditions and damage level was established. It is important to analyze the dynamic characteristics of mulberry in the process of drop. This study can be

“…The mechanical parameters that can be used to quantitatively assess the damage degree of fruits mainly include damage area, damage volume, impact energy, absorbed energy, impact acceleration, peak force and maximum stress. [11][12][13] A large number of studies on the mechanical properties of fruit have been reported. An et al 14 investigated the tissue damage mechanism of strawberries by compression tests at different velocities and found that the absorbed energy was a suitable and easily measured mechanical parameter for evaluating the damage degree of strawberries.…”

“…Wang et al 15 used the modulus of elasticity to characterize the damage degree of litchi, and the effect of impact times and absorbed energy on the damage degree of litchi was investigated. Yeşim et al 16 used electronic fruit (IRD) to simulate impact tests on peaches, which recorded the peak impact acceleration and velocity changes. The damage thresholds for different varieties of peaches were determined by evaluating the relationship between the peak acceleration and velocity of peaches and the damage area of peaches.…”

“…Mechanical parameters such as maximum force, maximum stress, average pressure, absorbed energy, restitution coe cient, impact velocity, and acceleration are the main parameters in characterizing the degree of impact damage of fruits [7][8][9]. Strope and Gołacki [10] designed a fruit collision device based on the principle of the single pendulum to record the maximum force, maximum stress, and permanent deformation of apples when they were impacted.…”

The quantitative description of the impact damage of yellow peaches is an essential basis for evaluating their quality and guiding their postharvest handling. In this study, the combined hyperspectral technology and mechanical parameters method were used to quantitatively investigate the impact damage of yellow peaches. Firstly, the mechanical parameters, which are damaged area, absorbed energy, maximum contact force, and maximum stress of yellow peaches, were obtained by the impact device. The statistical regression models between mechanical parameters and damage area were established, and the results showed that the absorbed energy and maximum contact force are the optimal parameters to characterize the impact damage of yellow peaches. Then, the raw spectra were preprocessed by three spectral pretreatment methods, which are standard normal variate (SNV), multiplicative scatter correction (MSC), and SG smoothing, respectively, and the feature wavelengths were selected by the competitive adaptive reweighted sampling (CARS), and the quantitative relationships between spectra and mechanical parameters were successfully modeled based on partial least squares regression (PLSR). The results showed that there is a strong linear correlation between the spectral data and the mechanical parameters, and the prediction performance of the SNV-CARS-PLSR model is best, and the RP and RMSEP of the damaged area, absorbed energy, maximum contact force, and maximum stress of it were 0.920 and 86.452 mm2, 0.845 and 1.303 J, 0.943 and 49.666 N, 0.660 and 0.146 MPa, respectively. In a word, this study shows that the combined hyperspectral technology and mechanical parameters method can be used to quantitatively assess the impact damage of yellow peaches, and guide the postharvest handling of fruits.
