Abstract

The contact parameters between lychee fruits and between fruits and packaging structures are unclear during lychee automatic packaging, which leads to low packaging efficiency. The work aims to calibrate the contact parameters of lychee particle simulation models using the Discrete Element Method (DEM) to provide theoretical support for the design of related packaging equipment. The EDEM software was used to establish particle models. The coefficients of restitution, static friction coefficients, and rolling friction coefficients between lychees and materials such as stainless steel, acrylic, and foam plastic were determined through collision rebound, slope sliding, and rolling experiments. Based on the results of angle of repose and steepest slope tests, the factors and levels of a second-order regression orthogonal rotational combination experiment were determined. The Response Surface Methodology (RSM) was then applied to optimize the multivariate quadratic equation for multiple objectives, ultimately determining the optimal combination of contact parameters between lychee fruits. The accuracy of the model was verified through lift-off cylindrical experiments and packaging experiments. The calibrated coefficients of restitution were 0.498 for stainless steel, 0.462 for acrylic, and 0.342 for foam plastic; the static friction coefficients were 0.356, 0.347, and 0.598 respectively; and the rolling friction coefficients were 0.037 5, 0.038 7, and 0.039 8, respectively. The optimized combination of contact parameters for lychee fruits was a coefficient of restitution of 0.243, a static friction coefficient of 0.374, and a rolling friction coefficient of 0.127. The error of piling angle between the simulated and physical experiments of was 3.59%. This study successfully calibrates the contact parameters of lychee particles, providing accurate and reliable simulation parameters that support the research of lychee physical properties and the design of packaging equipment, thereby achieving the research goal of improving packaging efficiency.
