According to the structure and force characteristics of the walking mechanism of the bridge inspection car, the pin-shaft sensor design test is used to study and obtain the maximum support load and the maximum driving force load of the traveling mechanism of a certain type of bridge inspection car. Based on ADAMS simulation and analysis software, the coordinates of the hinge points are designed parametrically to optimize the positions of the hinge points of the walking mechanism, so that the hinge point load is reduced by more than 30%, and the optimization effect is remarkable. Designing a new bridge test car walking mechanism, and its finite element analysis and experimental verification, the results show that the new type of walking mechanism of the lower stress to meet the product requirements.
