Abstract: Vehicle-mounted tensioning equipment must balance heavy-duty off-road capability with structural compactness. As a critical load-bearing component, the platform is required to meet both high-strength and lightweight design demands. Since the installation of tensioning module significantly affects the platform's structural rigidity, optimizing the platform structure has become a key aspect of equipment development.This study established a physical model based on load characteristics and boundary conditions, and carried out static analysis and topology optimization, followed by structural reconstruction and reanalysis of the optimized design. The results showed that, while ensuring structural safety, the platform's weight was reduced by approximately 20%, achieving significant lightweighting. This provides theoretical support and an optimization basis for the structural design and performance improvement of vehicle-mounted tensioning equipment work platforms.
