Abstract :In this study, the design and optimisation processes of the link to be used in the steel track undercarriage system of a tracked vehicle are summarised. In the first stage, a preliminary model was created by considering existing design examples and constraints. Two different Finite Element (FE) models were built using the maximum driving torque and track - ground contact forces. According to the results obtain from the analyses, three critical regions where stress concentration occurs, were identified. Seven structural design parameters were chosen to minimise stress concentrations in these regions. A Design of Experiments-based optimisation study was performed using these parameters. After obtaining new dimensional values, a new link design was created. The FE analyses conducted for maximum torque case showed that approximately decrease of 61%, 55%, and 20% was obtained in terms of stress concentration at the first, second, and third critical regions, respectively. Under the effect of vertical and lateral forces, the improvement percentages are 63%, 26%, and 31%, in the same order. It was observed that the stress values obtained at the critical regions of the new design under the failure loads, were below the permissible values.
