Abstract: As the core component of roigid mining vehicles, the A-frame must have high strength, high reliability and fatigue resistance. Through the analysis software, this paper first conducts multi-case simulation analysis on the newly developed A-frame of a rigid mining vehicle, verifies the strength performance of the new design scheme, and evaluates the risks. Then based on the analysis results, material and process optimizations are applied to multiple structural components. Finally, the optimization plan is analyzed and verified, sample development, loading verification, and the two-year mining area reliability verification is completed. The study achieves dual optimization of performance improvement and weight reduction for the A-frame. It is proved that by adopting simulation analysis optimization methods during the structural product scheme design phase, the reliability of the A-frame is not only improved, but also improved project development efficiency and shortened product research and development cycle
