Static vehicle and bridge model wind tunnel synchronous testing device

The invention discloses a static vehicle and bridge model wind tunnel synchronous testing device. The testing device comprises a pair of steel brackets, wherein the steel brackets and end plates are fixedly connected through steel tubes to form a framework system; vehicle test balances are in sliding connection with horizontal first sliding slots fixed to the steel brackets, and a rigid thin rod is installed between the corresponding vehicle test balances on the steel brackets at the two sides; a vehicle model is installed on the rigid thin rod in a sliding mode; bridge segment model test balances are in sliding connection with vertical second sliding slots fixed to the end plates; and a bridge segment model is connected between the two bridge segment model test balances, the bridge segment model is a uniform section in the length direction, and the bridge segment model keeps non-contact with the vehicle model in the vertical direction. Through the testing device, when a vehicle existson a bridge, aerodynamic
