Investigation of Sea Buckthorn Vibration Shedding Damage Based on Experiment and Finite Element Method

ABSTRACT To address fruit and branch damage in mechanized sea buckthorn harvesting, this study investigates the dynamic response and damage mechanisms using the Finite Element Method (FEM) and vibration experiments. Vibration parameters were analyzed via Continuous Wavelet Transform (CWT). Key mechanical properties of branches were determined, and a fruit detachment acceleration model, along with damage indices, was established. Results indicated a fruit rupture strength of 1.577 MPa. The main contribution lies in integrating multiple approaches to elucidate vibration‐induced damage mechanisms and quantify critical harvesting parameters. The use of optimized vibration parameters, with a frequency of 16.3 Hz and an acceleration of 2.5 g ( g = 9.80 m/s 2 ), was shown to improve the fruit harvest rate while minimizing damage. This study offers essential technical insights for designing efficient sea buckthorn vibration harvesters.
