Due to the complex operating environment of combine harvesters, uneven terrain, multiple vibration sources, and transmission systems, failures easily occur in critical working components, especially bolted connections vibrating screen. To address these issues, this study first established a bolt-tightening mechanical model. Secondly, finite element simulation preload force was performed using Ansys Workbench software (2023R2). The results showed that bolt head area exhibits ring-shaped strain distribution. determine state loosening, single-bolt loosening test conducted. experimental indicated when pressure decreased 78.4 N torque 0.5 N·m, intensified, value sharp decreasing trend. These values can be defined as threshold, providing an important reference basis for subsequent monitoring early warning. Finally, more realistically simulate actual conditions, harvester field By arranging triaxial acceleration sensors on screen, signals were collected under both low-speed high-speed conditions. Time–frequency analysis extract characteristic each measurement point. shaft structure screen at relatively high level, indicating part is subjected large load. Furthermore, frequency domain feature revealed components are complex, which further increases risk loosening. This provides in-depth characteristics screen’s harvesters. provide theoretical technical support online structure.
