The bolster, a critical component in three-piece casting bogies, bears half of the wagon’s total weight. This study investigates the strain distribution of an optimized bolster through experimental testing. The optimized bolster is fabricated from a modified material exhibiting enhanced impact properties compared to conventional grades. Additionally, minor geometric refinements, such as a slight increase in the fillet radius at sharp edges and around holes, have been implemented to mitigate local stress concentrations. Strain measurements are acquired at 114 points on the bolster surface. A numerical model is developed and subsequently validated against these experimental results, enabling a detailed investigation of the bogie’s behavior and facilitating the proposal of new geometrical modifications. The discrepancy between the experimental and simulated results averaged approximately 10%, a margin considered acceptable. Throughout all measurement points, the strain remains within the elastic range, gradually returning to zero upon load removal. The calculated factor of safety for the bolster approximates 2. Ultimately, based on these findings, recommendations are provided for further modifications to the bolster design, aimed at enhancing its factor of safety and potentially increasing its axle load capacity.
